        Test of Time Reversal Invariance at COSY 25m
        Time-reversal symmetry is one of the most fundamental of symmetries in nature. CP-violation phenomena, which can be regarded as equivalent to T-violation provided that CPT is conserved, have been observed in the $K^0$ and $B$ systems. However, it is well known that in the SM this CP violation is many orders of magnitude too small to account for the apparent asymmetry between matter and anti-matter in the Universe. The current upper limit for (parity-conserving) time-reversal non-invariance was obtained through measuring the total cross sections of a polarized neutron beam incident on a Holmium target. However, the interpretation of such data at a fundamental level is difficult due to the use of a complex nuclear targets. The theoretical understanding of measurements with a polarized proton beam and a deuterium target would certainly be much cleaner. In order to improve the Holmium limit by an order of magnitude, the parity-conserving time-reversal violating observable $A_{y,xz}$ in proton-deuteron forward scattering would have to be measured with an accuracy of $10^{-6}$. Such a measurement is planned as an internal target transmission experiment, requiring the use of a polarized proton beam and a tensor polarized deuterium target. In this experiment the COSY ring would serve simultaneously as accelerator, ideal forward spectrometer, and detector. An openable storage cell and holding magnetic field system have recently become available at the low beta section of the COSY ring where the PAX studies are undertaken. Much more stable beam conditions can be achieved here than elsewhere in the ring. Using the large acceptance PAX detector system, in addition to performing a measurement of $A_{y,xz}$, it is also possible to search for violation of time-reversal invariance in differential observables. Results from the first preparatory run and future perspectives will be presented.

        Enhanced lepton flavour violation in the supersymmetric inverse seesaw 25m Room 2

        Room 2

        IST Congress Center

        We have highlighted that the Higgs-mediated penguin diagrams contributing to lepton flavour violating observables like $\tau \rightarrow \mu \mu \mu$ or $B_{d}^{0} \rightarrow e \mu$ are enhanced by as much as two orders of magnitude in the supersymmetric inverse seesaw model. It has been recently pointed out that the Z-mediated contributions could be enhanced in extensions of the MSSM that accommodate neutrino masses. In this talk, we will present these contributions and their enhancements due to the inverse seesaw. We will also discuss key signatures of our model, especially a surprising non-decoupling behaviour, and how they can be used to constrain the supersymmetric inverse seesaw.

        Fermion mixing with geometrical CP violation and its tests at the LHC 25m
        We construct for the first time a flavor model, based on the smallest discrete symmetry Delta(27) that implements spontaneous CP violation with a complex phase of geometric origin, which can actually reproduce all quark masses and mixing data. We show that its scalar sector has exotic properties that can be tested at the LHC.

        Neutrino mass and baryon asymmetry in two right-handed neutrino model 25m
        We discuss the Standard Model which extended by two right-handed neutrinos. In this case, the tiny neutrino masses observed by neutrino oscillation experiments and the baryon asymmetry of the universe (BAU) can be explained by these right-handed neutrinos, simultaneously. Moreover, we focus on the testability of right-handed neutrinos by the direct search experiments. Then, we investigate right-handed neutrinos lighter than the charged kaon. Even if the masses of right-handed neutrinos are such small, the seesaw mechanism can work due to the suppressed neutrino Yukawa couplings. Furthermore, from the small Yukawa couplings the right-handed neutrinos deviate form thermal equilibrium in the early universe, and the BAU can be generate by Baryogenesis via right-handed neutrino oscillation. Therefore, we study to test the origin of neutrino mass and BAU with searching for right-handed neutrinos. In this scenario, we evaluated the allowed parameter space from experimental and cosmological bounds of right-handed neutrinos. The right-handed neutrinos can be produced by meson decays through the mixing with left-handed neutrinos. Then, some experiments using meson decays have set upper bounds for interaction strength of right-handed neutrinos because the right-handed neutrinos have not been discovered yet. On the other hand, to keep the successful Big bang nucleosynthesis the lifetime of right-handed neutrinos are restricted. As a result, we found Majorana phase are limited in the allowed parameter space in inverted mass hierarchy case, and calculated the impacts on neutrinoless double beta decay. In addition, we showed a possibility that all unknown parameters in this model might be determined by realization of the observed value of BAU, future oscillation experiments and direct search for right-handed neutrinos.

        Neutrino mass from d>5 effective operators in an SU(5) GUT with discrete symmetry 25m
        New physics models often come with an extended Higgs sector and additional (discrete) symmetries. We will show that in these models neutrino mass can be generated by higher-dimensional effective operators, which can be systematically studied. As a consequence new physics will appear at the TeV scale, which has phenomenological implications at the LHC, such as processes with displaced vertices and lepton number violation. We will further discuss how these models can be embedded into SU(5) GUT models with discrete symmetries. Additional heavy d-like quarks that appear in the SU(5) multiplets will be studied with regard to cosmological constraints.

        CP violation and Standard Model tests in charmless hadronic B decays 25m
        We investigate the potential of QCD- and QED-penguin dominated non-leptonic B -> K + {pi, eta', phi, omega, rho} decays in the framework of QCD factorisation to constrain non-standard effects, especially in direct and mixing-induced CP asymmetries. Contrary to the conventional treatment of the model-dependent parameters associated with divergent weak annihilation (and hard-scattering) contributions at sub-leading order, we determine them from existing experimental data, instead of variation in a limited range. This allows us to provide Standard Model predictions for PP and PV light final states, reanalyze the B -> K pi puzzle, and study new physics scenarios, such as model-independent gluon- and Z-penguin contributions. In the case of the Z-penguin we take into account complementary data from semi-leptonic b -> s-transitions. Further we discuss the impact of future experimental accuracy at LHCb and Super-Flavor factories.

        The S3 flavour symmetry: quarks, leptons and Higgs sectors 25m
        We present a brief overview of the minimal S3 invariant extension of the Standard Model in which the concept of flavour is extended to the Higgs sector by introducing in the theory three Higgs fields which are SU(2) doublets. The mass matrices of quarks and leptons are reparametrized in terms of their eigenvalues, thus allowing to express all entries in the mixing matrices, V_CKM and U_PMNS, in terms of mass ratios, and from a numerical analysis, in excellent agreement with the most recent experimental data. In the leptonic sector the S3xZ2 symmetry implies a non-vanishing ans sizeable reactor mixing angle, theta_13 ~ 9.2deg, in very good agreement with experimental data.

        In this work, we study the implications in the neutrino sector of a Z_4 flavour symmetry in the context of a non-supersymmetric SU(5), where both up- and down-quark mass matrices have the nearest-neighbour interaction form. The model is composed by one 5 and one 45 Higgs representations and in addition to the standard fermionic content, it is added three 24 fermionic representations. In such case, the light neutrinos got mass through the usual type I + III seesaw mechanism.

        A Model for Large theta13 Constructed using the Eigenvectors of the S4 Rotation Matrices 25m
        A procedure for using the eigenvectors of the elements of the representations of a discrete group in model building is introduced and is used to construct a model that produces a large reactor mixing angle, sin^2(theta13)=2/3 sin^2(pi/16), in agreement with recent neutrino oscillation observations. The model fully constrains the neutrino mass ratios and predicts normal hierarchy with the light neutrino mass, m1~25 meV. Motivated by the model, a new mixing ansatz is postulated which predicts all the mixing angles within 1sigma errors.

        Triplet Scalar Dark Matter and Leptogenesis in an Inverse See-Saw Model of Neutrino Mass Generation 25m
        We propose a UV-completion of the inverse see-saw scenario using fermion SU(2)L triplet representations. Within this framework, a variation of the standard thermal leptogenesis is achievable at the O(TeV) scale, owing to the presence of a viable Dark Matter candidate. This baryogenesis scenario is ruled out if a triplet fermion is observed at the LHC. The Dark Matter is given by the lightest neutral component of a complex scalar SU(2)L triplet, with mass mDM > 1290 GeV. The scalar sector, which is enriched in order to account for the small neutrino masses, is treated in detail and shows potentially sizable Higgs boson h → γγ rates together with large h invisible branching ratios.

        Multi-Component Dark Matter System with non-standard annihilation processes 25m
        Conversions and semi-annihilations of dark matter (DM) particles in addition to the standard DM annihilations are considered in a three-component DM system. We find that the relic abundance of DM can be very sensitive to these non-standard DM annihilation processes, which has been recently found for two-component DM systems. To consider a concrete model of a three-component DM system, we extend the radiative seesaw model of Ma by adding a Majorana fermion $¥chi$ and a real scalar boson $¥phi$, to obtain a $Z_2¥times Z'_2$ DM stabilizing symmetry, where we assume that the DM particles are the inert Higgs boson, $¥chi$ and $¥phi$.It is shown how the allowed parameter space, obtained previously in the absence of $¥chi$ and $¥phi$, changes.The semi-annihilation process in this model produces monochromatic neutrinos. The observation rate of these monochromatic neutrinos from the Sun at IceCube is estimated. Observations of high energy monochromatic neutrinos from the Sun may indicate a multi-component DM system.

        The LUX Experiment: Status and Future Plans 25m
        LUX (Large Underground Xenon) is a dark matter detection experiment using a 350 kg dual-phase Xe TPC. It will surpass all existing dark matter limits for WIMP masses above 10 GeV within weeks of beginning its science run, and its goal is to reach a WIMP-nucleon cross-section sensitivity of 2e-46 cm^2 for a 40 GeV WIMP after 300 days of running (an order of magnitude lower than the current best limit). LUX was already tested during a surface run in the Sanford Lab at Homestake, with all subsystems in their final configuration. This marked the first successful use of technologies proposed for tonne-scale detectors, such as a water tank for shielding and thermosyphon cooling. During this surface run the detector was calibrated using radioactive sources, showing an excellent light collection and demonstrating the potential for a very low (~1 keV) energy threshold. LUX is currently installed in the Sanford underground laboratory, and close to starting its first science run. Plans for the LZ experiment, the next generation detector with a mass of 7 tonnes, will also be discussed in this talk.

      Instituto Superior Técnico Avenida Rovisco Pais,1 1049-001 Lisboa, Portugal
      I provide a comparative study of the likelihood and naturalness of the most popular SUSY models, consistent with recent LHC results for the Higgs. I show that if one regards the EW minimum conditions as constraints that fix the EW scale, the (constrained) likelihood of such models to fit the EW data is changed and is actually smaller (worse) than usually thought, being equal to the ratio L/Delta of the usual likelihood L and the traditional fine tuning measure ("in quadrature") Delta of the EW scale. Equivalently chi^2 receives a correction, so far ignored: chi^2_new=chi^2_old+2*Log[Delta]. As a result a large likelihood (or min chi^2/d.o.f.) actually demands a large ratio L/Delta, from which a model-independent bound is derived for the EW scale fine-tuning: Delta<

        Higgs Decays in Low Scale Type I Seesaw Scenarios 25m
        The couplings of low scale type I seesaw scenarios are severely constrained by the requirement of reproducing the correct neutrino mass and mixing parameters, by the non-observation of lepton number and charged lepton flavour violating processes and by electroweak precision data. We show that all these constraints still allow for the possibility of an exotic Higgs decay channel into a light neutrino and a heavy neutrino with a sizable branching ratio. We also estimate the prospects to observe this decay at the LHC and discuss its complementarity to the indirect probes of the low scale type I see-saw model from experiments searching for lepton flavour violation.

        I will present the fit of the Higgs boson rates, based on all the latest collider data, in the effective framework for any Extra-Fermion(s) [EF]. The variations of the fit with the effective parameters will be described; the obtained fits can be better than in the Standard Model (SM). I will show how the determination of the EF loop-contributions to the Higgs couplings with photons and gluons is relying on the knowledge of the top and bottom Yukawa couplings; for determining the latter coupling, the relevance of the investigation of the Higgs production in association with bottom quarks will be emphasized. In the instructive approximation of a single EF, I will show that the constraints from the fit already turn out to be quite predictive. In the case of an unmixed extra-quark, non-trivial fit constraints will be pointed out on the Yukawa couplings for masses up to ~200 TeV. In particular, I will define the extra-dysfermiophilia, which is predicted at 68.27% C.L. for any single extra-quark; an example will be given. I will finally demonstrate that among any components of SM multiplet extensions, the extra-quark with a -7/3 electric charge is the one preferred by the present Higgs fit.

        RGE Behaviour of SUSY with a U(2)^3 symmetry 25m
        The first LHC results seem to disfavor any constrained MSSM realization, with universal conditions at the SUSY-breaking scale. A more motivated scenario is given by split-family SUSY, in which the first two generations of squarks are heavy, compatible with a U(2)^3 flavour symmetry. We consider this flavour symmetry to be broken at a very high scale and study the consequences at low energies through its RGE evolution. Initial conditions compatible with a split scenario are found, and the preservation of correlations from minimal U(2)^3 breaking are checked. The various chiral operators in $\Delta F=2$ processes are analyzed, and we show that, due to LHC gluino bounds, the (LL)(RR) operators can not always be neglected.

        Beaming Neutrino across the Earth to test neutrino mixing, symmetry and mass hierarchy 25m
        We considered the longest baseline neutrino oscillation available, crossing mostof the Earth diameter, may improve the measurement and disentangle at best any hypothetical CPT violation within MINOS bounds, while testing at highest rate tau and even the anti tau appearance. The μ and anti muon disappearance correlated with tau appearance is considered for those largest distances. We thus propose a beam through the Earth, within an OPERA-like experiment from CERN (or FermiLAB), in the direction of ICECUBE-DeepCore detector at the South Pole. The ideal energy lay at 21 GeV energy, to test the disappearance or (for any tiny CPT violation) the partial neutrino μ appearance. The tau appearance signal is above (or within) 10 sigma in a year, even for 1% OPERA-like experiment. Peculiar configurations for theta 13 and hierarchy neutrino mass test may also be better addressed by a Deep Core-PINGU array detector beaming μ neutrino and observing an electon one at 6 GeV energy windows.

        Measurement of the ground-state hyperfine splitting of antihydrogen at CERN 25m
        The ASACUSA collaboration at the Antiproton Decelerator of CERN is planning to measure the ground- state hyperfine splitting of antihydrogen using an atomic beam line. The setup consists of a cusp trap as a source of partially polarized antihydrogen atoms emitted toward a radiofrequency spin-flip cavity. A superconducting sextupole magnet serves as spin analyser before the detection of the atoms is an antihydrogen detector. Monte Carlo simulations show that the antihydrogen ground-state hyperfine splitting can be determined in a beam at a relative precision of ~ 10^(−7). Antihydrogen is the simplest atom consisting entirely of antimatter. Since its matter counterpart is one of the most precisely measured atoms in physics, a comparison of antihydrogen and hydrogen at the 10^(−7) level would already offer one of the most sensitive tests of CPT symmetry. My talk will discuss the theoretical background and present the latest developments in the setup as well as the coming years program to achieve the above mentioned precision.

        Hyperfine Structure of Antiprotonic Helium and the Antiproton Magnetic Moment 25m
        Antiprotonic helium [1] is an exotic three-body system consisting of a helium nucleus, an electron and an antiproton. The antiproton occupies highly excited metastable states, which allows it to be studied by laser and microwave spectroscopy techniques. By comparing the experimental results with state-of-the-art three-body QED calculations, fundamental properties of the antiproton can be extracted, yielding some of the most precise tests of CPT symmetry in the hadron sector. This way the most precise value of the antiproton mass has been obtained from the laser spectroscopy of antiprotonic helium [2]. The hyperfine structure (HFS) of antiprotonic helium arises from the interaction of the magnetic moments related to the electron spin and the antiproton angular momentum and its spin. Due to the high angular momentum of metastable states, dominant splitting arises from the interaction of electron spin and antiproton angular momentum, while the interaction of the antiproton spin with other moments leads to a smaller splitting. Using a laser-microwave-laser method [3] the most precise value of the magnetic moment of the antiproton was obtained [4] in antiprotonic 4He from the difference of the observed HFS transitions. Recently also the hyperfine structure of antiprotonic 3He was observed for the first time [5]. Its more complex hyperfine structure constitutes a more rigorous test of three-body bound-state QED theory. References [1] R.S. Hayano, M. Hori, D. Horvath, and E. Widmann, Rep. Prog.

        Testing the Pauli Exclusion Principle for Electrons 25m
        One of the fundamental rules of nature and a pillar in the foundation of quantum theory and thus of modern physics is represented by the Pauli Exclusion Principle. We know that this principle is extremely well fulfilled due to many observations. Numerous experiments were performed to search for tiny violation of this rule in various systems. The experiment VIP at the Gran Sasso underground laboratory is searching for possible small violations of the Pauli Exclusion Principle for electrons leading to forbidden X-ray transitions in copper atoms. VIP is aiming at a test of the Pauli Exclusion Principle for electrons with high accuracy, down to the level of 10^(-29) - 10^(-30), thus improving the previous limit by 3-4 orders of magnitude. 
 The experimental method, results obtained so far and new developments within VIP2 (follow-up experiment at Gran Sasso, in preparation) to further increase the precision by 2 orders of magnitude will be presented.

The resulting time-dependent diagrammatic perturbation series are free of pinch singularities without the need for quasi-particle approximation or effective resummation of finite widths. Introducing a physically meaningful definition of particle number densities, we derive master time evolution equations for statistical distribution functions, which are valid to all orders in perturbation theory and to all orders in a gradient expansion.

        We carry out a detailed analysis of a minimal $S_3$-invariant extension of the Standard Model, with an extended $S_3$-Higgs sector. Within this extended $S(3)$-Standard Model, we study the trilinear Higgs couplings and its dependence on the details of the model, even when the lightest Higgs boson mass is taken to be a fixed parameter. We study quantitatively the trilinear Higgs couplings, and compare these couplings to the corresponding Standard Model trilinear Higgs coupling in some regions of the parameter space. A precise measurement of the trilinear Higgs self coupling will also make it possible to test this extended $S(3)$-Standard Model which has a different trilinear Higgs couplings as compared to the Standard Model. We present analytical expressions for the trilinear Higgs couplings.

        Charged Higgs bosons in single top production at the LHC 25m
        We show that a light charged Higgs boson signal via tau nu decay can be established at the Large Hadron Collider also in the single top mode. This process complements searches for the same signal in the case of charged Higgs bosons emerging from t¯t production. The models accessible include the Minimal Supersymmetric Standard Model (MSSM) as well a variety of 2-Higgs Doublet Models (2HDMs). High energies and luminosities are however required, thereby restricting interest on this mode to the case of the LHC running at 14 TeV with design configuration.

        B -> D(*) tau nu Decays in the 2HDM 25m
        We analyze the recent experimental evidence for an excess of $\tau$-lepton production in several exclusive semileptonic $B$-meson decays in the context of two-Higgs-doublet models. These decay modes are sensitive to the exchange of charged scalars and constrain strongly their Yukawa interactions. While the usual Type-II scenario cannot accommodate the recent BaBar data, this is possible within more general models in which the charged-scalar couplings to up-type quarks are not as suppressed. Both the $B\to D^{(*)}\tau\nu_\tau$ and the $B\to\tau\nu_\tau$ data can be fitted within the framework of the Aligned Two-Higgs-Doublet Model, but the resulting parameter ranges are in conflict with the constraints from leptonic charm decays. This could indicate a departure from the family universality of the Yukawa couplings, beyond their characteristic fermion mass dependence. We discuss several new observables that are sensitive to a hypothetical charged-scalar contribution, demonstrating that they are well suited to distinguish between different scenarios of new physics in the scalar sector, and also between this group and models with different Dirac structures; their experimental study would therefore shed light on the relevance of scalar exchanges in semileptonic $b\to c\,\tau^-\bar\nu_\tau$ transitions

        Results from the ICARUS experimental search in the LSND anomaly region 25m
        Icarus is the largest liquid Argon TPC detector ever built (~600 ton LAr mass). It smoothly operates underground at the LNGS laboratory in Gran Sasso since summer 2010, collecting data with the CNGS beam and with cosmics. Liquid argon TPCs are really ``electronic bubble chambers'' providing a completely uniform imaging and calorimetry with unprecedented accuracy on massive volumes. Icarus is internationally considered as a milestone towards the realization of next generation of massive detectors (~tens of ktons) for neutrino and rare event physics. In particular the experimental search for a nu_e signal in the “LSND anomaly” region in the CNGS beam will be presented. This result strongly limits the window of opened options for the LSND anomaly, reducing the remaining effect to a narrow region centered around ∆m2 , sin2 (2θ) = (0.5eV2 , 0.05) where there is an over-all agreement (90% CL) between the present ICARUS limit, the published limits of KARMEN and the published positive signals of LSND and MiniBooNE collaborations. The results on the precise measurement of the neutrino speed using the CNGS bunched beam will be presented too.

        The SNO+ experiment: status and overview 25m
        SNO+ is a multi-purpose Neutrino Physics experiment, succeeding to the Sudbury Neutrino Observatory by replacing heavy water with liquid scintillator. Its scientific goals are the search for neutrinoless double-beta decay, the study of solar neutrinos and antineutrinos from reactors and the Earth's natural radioactivity, as well as supernovae neutrinos. The experimental advantages of SNO+ are the possibility of loading large quantities of double-beta decaying isotope in the liquid scintillator volume, and the very low backgrounds allowed by the deep underground location and radiopurity of the employed materials. The installation of the detector at SNOLAB is being completed, and commissioning has already started, with a dry run. Filling with water and later, with scintillator, will start next year. This talk will summarize the Physics goals of SNO+, as well as the main detector developments.

        Status of the CUORE experiment 25m
        One of the fundamental open questions in elementary particle physics is the value of the neutrino mass and its nature of Dirac or Majorana particle. Neutrinoless double beta decay (DBD0v) is a key tool for investigating these neutrino properties and for finding answers to the open questions concerning mass hierarchy and absolute scale. Experimental techniques based on the calorimetric approach with cryogenic particle detectors are proved to be suitable for the search of this rare decay, thanks to high energy resolution and large mass of the detectors. The CUORE (Cryogenic Underground Observatory for Rare Events) experiment will search for DBD0v in Te-130. The CUORE setup consists in an array of 988 tellurium dioxide crystals, operated as bolometers, with a total mass of about 230 kg of Te-130. The experiment is under construction at the Gran Sasso National Laboratory in Italy. As a first step towards CUORE, a tower prototype (CUORE-0) has been assembled and is running. In this talk a detailed description of the CUORE-0 tower, its performances and the expected sensitivity will be given. The status of the CUORE experiment, its critical points and its expected sensitivity on the base of what we will learn with CUORE-0 will then be discussed.

        Radioactive UHECR painting TeVs Gamma Anisotropy and first PeV observed neutrinos 25m
        UHECR (Ultra High Energy Cosmic Rays) were expected to be protons, whose spectra suffer of photopion opacity on cosmic CMB, the so called GZK cut off; AUGER did claimed on 2007 that such events were along the expected Super-Galactic plane with GZK cut off. However the same AUGER composition was favoring nuclei (and not nucleon); the recent absence of narrow angle clustering of UHECR as expected by protons, the missing of events along nearest Cluster Virgo, the wide spread angles of UHECR along Cen A, the more diffused events are in disagreement with first proton-UHECR-Super Galactic AUGER understanding. We claimed on 2008 a light nuclei role for Cen A crowded area. On the other side the ICECUBE absence of TeVs neutrino clustering or anisotropy, its spectra steepening is favoring mostly a ruling atmospheric neutrino noise up to tens TeV. However recent two PeV neutrino event cannot easily coexist or being extrapolate with such atmospheric ruling scenario, nor with GZK cut off (either nucleon or nuclei) secondaries expected spectra. We suggested and we reconfirm that an radioactive light and heavy UHECR component, while decaying in flight, may paint in the sky (by gamma, electrons and neutrinos) their trajectories and bending, connecting UHECR with TeV gamma anisotropy in ARGO-ICECUBE, as well offering a very realistic source of first observed PeV neutrinos.

        THREE NEUTRINO OSCILLATIONS IN THE EARTH: AN ANALYTIC TREATMENT 25m
        We use the Magnus expansion of the evolution operator in the adiabatic basis to find an approximate solution to the problem of three-neutrino oscillations in a medium with a symmetric, but otherwise arbitrary, density profile. We use an expression of the evolution operator for the neutrino system written as the product of three factors, each of them corresponding to an effective two-neutrino problem for a low or a high energy regime. By virtue of this factorization our approximation works well over a wide range of energies. When applied to the case of atmospheric neutrinos traversing the Earth, the oscillation probabilities thus calculated show good agreement with numerical results.

      CPT Violation in Early Universe and Leptogenesis/Baryogenesis 45m Main Auditorium

      I will discuss ways by means of which CPT in early epochs of the Universe may be violated, leading initially to an asymmetry in the populations of leptons versus antileptons (Leptogenesis), which may then be communicated to the baryon sector (via Baryon-Lepton-number (B-L) conserving processes) to produce the observed Baryon Asymmetry (Baryogenesis). These include: space-time curvature/spin coupling in non-standard (Lorentz-violating) geometries of the early Universe, such as axisymmetric black-hole geometries and certain Bianchi cosmologies or propagation in stochastically fluctuating space-time geometries of Finsler type, geometries with Kalb-Ramond torsion backgrounds and D-brane defect foam. In all such models CPT Violation occurs as a result of different dispersion relations induced between particles and antiparticles in the above backgrounds. In the D-brane (quantum-gravity) foam model there is a preferential role of neutrinos in coupling with the foam, which is due to electric charge conservation for specifically stringy reasons. Such models may then serve as ways of generating baryongenesis from leptogenesis without the need for extra sources of CP violation.

      An overview of supersymmetry searches will be presented, covering collider experiments, direct and indirect searches for supersymmetric dark matter. Recent LHC and Tevatron experimental results will be reviewed, and the constraints from B-meson decays will be reported. Implications for supersymmetry of the latest direct and indirect searches will be thoroughly discussed. The focus will be on the complementarity of the various probes -particle and astrophysical- for constraining Supersymmetry.
