  3. 7. Searches for Higgs and Higgs-like particles at LHCb
    Valdir Salustino Guimaraes (Univ. Federal do Rio de Janeiro (BR))

    Working Group 1
    talk
    The LHCb detector is a forward single arm spectrometer designed primarily for the study of CP-violation and other rare phenomena in the decays of beauty and charm particles. LHCb is very powerful in probing New Physics by performing indirect searches. Nevertheless, a program of direct searches for Higgs and Higgs-like particles also exists. Here we present some recent results and perspectives.

  4. 49. Composite Two Higgs doublet Models
    Dr Enrico Bertuzzo (CEA-Saclay)
    17/09/2013, 15:00
    Working Group 1
    talk
    After a brief introduction on the physical motivation for Composite Higgs models, I will discuss cosets leading to Composite Two Higgs Doublet Models. I will analyze in detail the problem of tree level custodial symmetry breaking and how this problem can be solved, as well as the specific embedding for fermion fields that allow to avoid Higgs mediated Flavor Changing Neutral Currents.

  5. 103. An 3HDM with $S_3$ symmetry, dark matter and two inert doublets without FCNC
    Dr Ana Machado (UFABC)
    17/09/2013, 15:40
    Working Group 1
    talk
    We propose a new mechanism to suppress the flavor changing neutral currents in a three-Higgs doublet extension of the standard electroweak model. This mechanism has three ingredients: i) The three SU(2) Higgs scalar doublets transform as the reducible representation triplet of the discrete S3 symmetry that breaks to the irreducible representations, a doublet and a singlet; ii) an appropriate...

  6. 47. Is the 125 GeV scalar the neutrino superpartner?
    Dr Carla Biggio (Università di Genova, Italy)
    17/09/2013, 16:20
    Working Group 1
    talk
    The scalar particle recently discovered at the LHC has the same gauge quantum numbers as the neutrino, so that one can ask if they can be one the superpartner of the other. In this talk I will discuss such a possibility, discussing a model where this is realised. This model has an interesting phenomenology at the LHC.

  7. 62. Search for the Higgs boson in VH(bb) and in the tau tau channel using the ATLAS detector
    Garoe Gonzalez Parra (IFAE - Barcelona (ES))
    17/09/2013, 17:30
    Working Group 1
    talk
    Since the discovery of a Higgs-like boson by the ATLAS and CMS experiments at the LHC, the emphasis has shifted towards measurements of its properties and the search for the search in the less sensitive channels in order to determine whether the new particle is the Standard Model (SM) Higgs boson. Of particular importance is the direct observation of the coupling of the Higgs boson to...

  8. 64. Probing the spin and parity of the Higgs Boson with the ATLAS Detector
    Manuela Venturi (Albert-Ludwigs-Universitaet Freiburg (DE))
    17/09/2013, 18:10
    Working Group 1
    talk
    The spin and parity of the recently discovered Higgs boson using the ATLAS detector and up to 25 fb-1 of 7 TeV and 8 TeV pp collision data collected in 2011 and 2012, was probed in the diboson (γγ, WW and ZZ) channels. These results and their combinations are presented.

  11. 17. Non-decoupling SUSY in LFV Higgs decays: a window to high $m_\text{SUSY}$ at the LHC
    Ernesto Arganda (IFLP-CONICET)
    19/09/2013, 10:00
    Working Group 1
    talk
    The recent discovery of a SM-like Higgs boson at the LHC, with a mass around 125-126 GeV, together with the absence of results in the direct searches for supersymmetry, is pushing the SUSY scale ($m_\text{SUSY}$) into the multi-TeV range. This discouraging situation from a low-energy SUSY point of view has its counterpart in indirect SUSY observables which present a non-decoupling behavior...

  12. 100. Linking Natural Supersymmetry to Flavour Physics
    Gero Gersdorff (ICTP-SAIFR)
    19/09/2013, 15:00
    Working Group 1
    talk
    With the aim of linking natural supersymmetry to flavour physics, a model is proposed based on a family symmetry G × U(1), where G is a discrete nonabelian subgroup of SU(2), with both F-term and (abelian) D-term supersymmetry breaking. A good fit to the fermion masses and mixing is obtained with the same U(1) charges for the left- and right- handed quarks of the first two families and the...

    Working Group 1
    talk
    Searches for signatures of beyond-the-standard-model higgs-like processes (eg charged higgs, double Higgs, A->Zh, ttbar, mumu), performed by CMS are presented, together with the perspectives at the LHC and future colliders.

  14. 136. Including theoretical uncertainties in Higgs fits
    Dr Sylvain Fichet (IIP, Natal, Brasil)
    19/09/2013, 17:30
    Working Group 1
    talk
    We review and develop consistent treatments of theoretical uncertainty (TU) in Higgs couplings fits, going beyond the current approximation of uncorrelated Gaussian TU. We emphasize two different conceptual lines in the treatment of TU either as a nuisance or as a bias. These two treatments are considered within both frequentist and Bayesian frameworks. We develop the bias approach in the...

  15. 82. Multiboson production and searches for anomalous gauge couplings at CMS
    Qiang Li (Peking University (CN))
    19/09/2013, 18:10
    Working Group 1
    talk
    We present studies of multiple boson production in pp collisions at 7 TeV and 8 TeV center-of-mass energy based on data recorded by the CMS detector at the LHC in 2011 and 2012. These include precision cross section measurements and investigation of kinematic distributions. The results are interpreted in terms of constraints on anomalous triple and quartic gauge couplings, together with future...

    Working Group 1
    talk
    I will talk about SUSY extension of SM with Dirac gauginos discussing the main advantages respect to the MSSM focusing in particular on R symmetric models. I will summarise the LHC phenomenology and how to obtain a 125 GeV Higgs in this framework.

    20/09/2013, 11:40
    Working Group 1
    talk
    After I presenting an analysis of the operators in supersoft SUSY breaking, I will discuss the requirements that must be satisfied by successful UV completions and the modifications of minimal supersoft mechanism needed to avoid negative mass squareds for adjoint scalars. I will then present a complete model of dynamical supersymmetry breaking resulting in realistic superpartner spectrum with...
