  65. 62. A search for indirect cosmological evolution of dark matter
    Dr Murli Verma (LUCKNOW UNIVERSITY)
    We propose a scenario of creation of dark matter from a decaying cosmological constant. Arc-like pattern found on the Cosmic Microwave Background Radiation (CMBR) were shown to result from the dark matter particles in the Q-phase of the interacting cosmological constant (ICC) model. In the present work, an investigation is made into how the corresponding decay of such dark matter...

  67. 112. Calibration Systems of the XENON1T Dark Matter Experiment
    Mr Jacques Pienaar (Purdue University)
    Aug/6
    The XENON1T detector, currently under construction at the Gran Sasso underground laboratory, will contain 3200kg of liquid xenon. A liquid noble element detector needs to be calibrated to understand its responses to both electronic and nuclear recoils. The additional volume of XENON1T poses new opportunities and new challenges. The greater volume makes it possible to use neutron double...

  69. 106. Charge migration in the germanium detectors of the EDELWEISS-III experiment
    Nadine Foerster (Karlsruhe Institute for Technology)
    Aug/6
    EDELWEISS-III is a direct dark matter search program looking for WIMPs using cryogenic germanium bolometers. A system of electrodes produces a homogeneous electric field in the inner region of the germanium crystals. The simultaneous readout of the heat increase and the ionization signal from scattered particles allows the discrimination of germanium nuclei recoils from electron recoils. For a...

  71. 99. Constraining light Shadow Z with low energy precision tests
    Wei-Ping Pan (National Tsing Hua University)
    Aug/12
    A neutral vector boson, dubbed shadow $Z'$, which stems from a hidden $U(1)_s$ gauge sector can weakly couple to the standard model fermions through the kinematic mixing between the $U(1)_s$ and the hypercharge $U(1)_Y$. If the shadow $Z'$ is light, $< m_Z$, it can easily evade all collider constraint as long as the kinematic mixing term is small. We study the feasibility of probing...

  72. 64. Cosmic Ray Excesses from Multi-component Dark Matter Decays
    Da Huang (N)
    AMS-02 collaboration published their measurement on the positron fraction in the cosmic rays, confirming the excesses by PAMELA. Also, the Fermi-LAT data on the total $e^+ + e^-$ flux also showed excess above 20 GeV. In this talk, I shall show that the multi-component decaying dark matter (DM) scenario can naturally explain these two anomalies. By performing the $χ^2$ fits, we find that two...

  73. 97. Dark matter and computational geometry
    Mr Devon Powell (SLAC/Stanford)
    Aug/6
    Traditional N-body simulations discretize the dark matter distribution into an ensemble of point particles. However, estimating the local density for a set of point particles is difficult due to Poisson noise. Abel et al. (2012) instead describe the phase-space distribution of dark matter as a 3D manifold tessellated into tetrahedra. This has the advantage of giving an unambiguous value...

  74. 113. Dark Matter Annihilations in the Causal Diamond
    Andrew Scacco (UC Davis)
    Aug/12
    We investigate the implications of dark matter annihilations for cosmological parameter constraints using the causal entropic principle. In this approach cosmologies are weighted by the total entropy production within a causally connected region of spacetime. We calculate the expected entropy from dark matter annihilations within the causal diamond and investigate the preferred values...

  75. 100. Dual-phase Liquid Xenon Detector Development at UCLA
    Mr Yixiong Meng (UCLA)
    Aug/12
    The current leading experiments of direct dark matter detection use liquid xenon as the detecting medium. The strongly motivated dark matter candidates Weakly Interacting Massive Particles (WIMPs) are expected to create nuclear recoils in the liquid xenon. During the long measurement period, the detectors face a great challenge of an overwhelming radioactive background in the form of...

  77. 110. Geometry from probability: A possible origin of dark energy or the inflaton
    Dr Chris Vuille (Embry-Riddle Aeronautical University)
    Aug/6
    A principle is proposed that relates probability to geometry. That principle is then used to motivate the introduction of nonlinear differential operators on spacetime manifolds. Such operators are difficult to handle mathematically, hence a geometric interpretation of the Universal Covering Group for tensors is undertaken. The principle can then be understood as equivalent to a Lagrangian of...

  78. 66. H.E.S.S. Analysis of Sgr A*
    Ms Helen Poon (Max Planck Insitut fur Kernphysik)
    The mysterious Galactic Center is an interesting region with frequent flaring activities from the radio to X-ray bands. However, VHE flux always remains steady. In 2012, a gas cloud G2 was discovered to be travelling straight to the GC. It is expected to pass the pericenter in 2014. During pericenter passage, it will be so closed to the GC that it will be completely disintegrated by the black...

  79. 98. Hidden Sector Dark Matter Models for the Galactic Center Gamma-Ray Excess
    Asher Berlin (University of Chicago)
    Aug/12
    The gamma-ray excess observed from the Galactic Center can be interpreted as dark matter particles annihilating into Standard Model fermions with a cross section near that expected for a thermal relic. Although many particle physics models have been shown to be able to account for this signal, the fact that this particle has not yet been observed in direct detection experiments somewhat...

  80. 91. Higgs Gravitational Interaction, Weak Boson Scattering, and Higgs Inflation in Jordan and Einstein Frames
    Dr Jing Ren (University of Toronto)
    Aug/12
    We study gravitational interaction of Higgs boson through the unique dimension-4 operator ξH^{\dag}HR , with H the Higgs doublet and R the Ricci scalar curvature. We analyze the effect of this dimensionless nonminimal coupling ξ on weak gauge boson scattering in both Jordan and Einstein frames. We demonstrate that the weak boson scattering amplitudes computed in both frames are equal in flat...

  81. 93. How dark matter, baryons, and radiation imprint scales on galaxy clustering today
    Zachary Slepian (H)
    Aug/12
    The growth of structure around the time of matter-radiation equality, z~3000, is determined by both the matter and radiation. Outside the sound horizon, inhomogeneities in the radiation contribute gravitationally to the growth of perturbations, as do inhomogeneities in the matter. In contrast, inside the sound horizon, the radiation inhomogeneities contribute less and less. This difference...

    Stephen Portillo (Harvard University)
    Aug/6
    The Large Area Telescope on the *Fermi* Gamma-ray Space Telescope has a point spread function with large tails, consisting of events affected by tracker inefficiencies, inactive volumes, and hard scattering; these tails can make source confusion a limiting factor. The parameter CTBCORE, available in the publicly available Extended *Fermi* LAT data, estimates the quality of each event's...

  87. 102. Inflation with an oscillating field
    Mr Yu-Hsiang Lin (Department of Physics, National Taiwan University)
    Aug/12
    We propose that if there is a massive scalar field oscillating at its vacuum during the slow-roll inflation, its settlement will distort the primordial power spectrum from the simple power law. At the scales which exit the Hubble radius during the oscillation, the power of curvature perturbations oscillates on top of the nearly scale-invariant spectrum. Assuming that the last stage of...

  88. 101. Loop Effects of an Effective Dark Matter Model on Dilepton Production
    Nirmal Raj (University of Oregon)
    Aug/6
    While LHC searches for new resonance states (Z' models) are ongoing in the neutral-current Drell-Yan process, one of the cleanest channels to seek New Physics, it is important to also look for non-resonant effects. In particular, box diagrams with hidden sector TeV-scale states can interfere with the Standard Model to produce spectacular dilepton spectra. To this end, I will motivate an...

    Mr Michael Baumer (Stanford University)

    The Large Synoptic Survey Telescope (LSST) will use a 3.2 Gigapixel CCD camera to conduct a deep ($M_r < 27.5$) wide-field survey of the Southern sky in six optical bands (u, g, r, i, z, and y) over 10 years. The science drivers of the survey, particularly precision measurements of weak lensing, place tight constraints on camera performance in terms of both photometry and galaxy shape...

    andrea addazi (I)
    Aug/12
    A Majorana mass for the neutron could result from non-perturbative quantum gravity effects peculiar to string theory. In particular, ``exotic instantons" in un-oriented string compactifications with D-branes extending the (supersymmetric) standard model could indirectly produce an effective operator $\delta m \, n^t n+h.c$. In a specific model with an extra vector-like pair of `quarks',...

  91. 68. Non-Existence of Black Holes with Non-Canonical Scalar Fields
    Mr Rahul Jha (DAMTP, University of Cambridge)
    Aug/6
    In this talk we'll study the existence of black holes with non-canonical scalar fields as matter source and prove a simple no-hair theorem which rules out the existence of stationary, asymptotically flat black holes possessing scalar hair for a wide class of such models. This applies in particular to K-essence theories like the ghost condensate model, and large sectors of the dilatonic ghost...

  92. 114. Numerical evolution of two autogravitating scalar fields with spontaneous symmetry breaking
    Hector Raul Olivares Sanchez (CINVESTAV)
    Aug/12
    We solve numerically the Einstein equations in spherical symmetry for a system of two coupled real scalar fields that exhibits spontaneous symmetry breaking, and where one of the fields, initially massless, acquires an effective mass due to the coupling. We study first the evolution of the homogeneous fields, and then we add Gaussian pulses in one of them. We find the evolution of the...

    Dong Woo Kang (Sungkyunkwan University (SKKU))
    Aug/6
    We present a model with universal extra dimensions in the presence of boundary localized kinetic terms for electoroweak gauge bosons. This model can realize that the lightest Kaluza-Klein particle is a mixture of KK $B^{1}$ and KK $W_{3}^{1}$. Depending on boundary localized parameter ($r_{B},r_{W}$) the KK dark matter is more like KK $Z$ or KK photon. We showed current bounds on...

    Alessandro Pilloni (Sapienza U.)
    Aug/12
    Since ten years ago a host of exotic resonances have challenged the ususal quarkonium picture. A number of ideas have been put forward to explain these new states, but a comprehensive framework is still missing. We present here results on $X(3872)$ production in $pp(\bar p)$ collisions obtained with Monte Carlo hadronization methods and illustrate what can be learned from their use to improve...

  96. 65. Prospects for testing models of coupled dark matter-dark energy via 21 cm Power Spectrum after Reionization
    Ricardo Landim (University of Sao Paulo)
    The hydrogen 21 cm line has been used as an interesting tool of cosmology, and among its several applications there is the possibility of testing models of modified gravity via comparing both modified gravity and $\Lambda$-CDM 21 cm Power Spectrum. The present work goes in the same direction, aiming to study models of interation between dark energy and dark matter using this approach. The...

Here we present a brief review of the linear theory of redshift space...

    Leila Ali Cavasonza (RWTH-Aachen)
    A very exciting challenge in particle and astroparticle physics is the exploration of the nature of dark matter. The striking evidences of the existence of dark matter are also the strongest phenomenological indications for physics beyond the Standard Model. A huge experimental effort is currently made at colliders and via astrophysical experiments to shed light on the nature of dark...

  114. 92. Ruling out bosonic repulsive dark matter in thermal equilibrium
    Mr Zachary Slepian (Harvard University)
    Aug/6
    Self-interacting dark matter, especially bosonic, has been considered a promising candidate to replace cold dark matter (CDM) as it resolves some of the problems associated with CDM. Here, we rule out the possibility that dark matter is a repulsive boson in thermal equilibrium. We develop the model first proposed by Goodman in 2000 and derive the equation of state at finite temperature....

    Lene Bryngemark (Lund University (SE))
    Aug/12
    The dijet final state at high transverse momentum probes the highest energies reached in a collider experiment. This corresponds to the largest reach in mass for the production of new particles, but also to resolving the smallest distances.

  117. 111. Signatures of Dark Matter Scattering Inelastically Off Nuclei
    Shayne Reichard (Purdue University)
    Aug/6
    Direct dark matter detection focuses on elastic scattering of dark matter particles off nuclei. In this poster, we investigate inelastic scattering in which the target nucleus is excited to a low-lying state of ~10-100 keV, with a subsequent prompt de-excitation. We calculate the inelastic structure factors of the odd-mass xenon isotopes based on state-of-the-art large-scale shell-model...

  118. 70. Spin-One Top Partner: Phenomenology
    Bithika Jain (Syracuse University)
    Aug/6
    Cai, Cheng, and Terning (CCT) suggested a model in which the left-handed top quark is identified with a gaugino of an extended gauge group, and its superpartner is a spin-1 particle. We perform a phenomenological analysis of this model, with a focus on the spin-1 top partner, which we dub the **swan**. We find that precision electroweak fits, together with direct searches for $Z^\prime$ bosons...

  120. 109. Systematic Sources of Uncertainty in NaI(Tl) Dark Matter Detectors
    Ms Cassie Reuter (Purdue University)
    Aug/6
    Despite over a decade of exploring everything from detector systematics to exotic dark matter models, there has yet to be a satisfactory explanation of the DAMA results. Construction is currently underway for an experiment that will be able to determine whether an environmental or operational parameter could be responsible for DAMA's signal. This experiment features a total of 32 three-inch...

  122. 105. The SuperCDMS Active Neutron Shielding Concept
    Geertje Heuermann
    Aug/12
    Future large scale cryogenic dark matter experiments – such as EURECA or SuperCDMS - will focus on the exploration of low mass WIMPS reaching for unparalleled sensitivities for the cross section of spin-independent WIMP-nucleon interactions. This requires an unprecedented suppression of the background in the nuclear recoil band down to 1 event/ton/year in the region of interest. External and...
