  1. 3. Higgs and New Physics

  2. 17. Searching for the Higgs bosons of the NMSSM
    Filippo Sala (IPhT CEA-Saclay)
    16/01/2015 09:25
    The search for signs of more scalars is a primary task of current and future experiments. In particular, in the next-to-minimal supersymmetric Standard Model, the extra Higgs bosons could well be the lightest new particles around. I will outline a possible overall strategy to look for the extra CP-even scalars, comparing the impact of measurements of the SM Higgs couplings with the direct...

  3. 21. A Light Singlet in Gauge Mediation
    Robert Ziegler (LPTHE)
    16/01/2015 09:39
    I will discuss the possibility of a light supersymmetric singlet below 100 GeV in the context of a very predictive model that combines the NMSSM and Gauge Mediation. This model has been originally proposed by Delgado,Giudice and Slavich, but the LEP bound had been imposed on the lightest Higgs state. We re-analyzed this model and found new interesting regions in the parameter space with a...

  4. 47. Bridging Composite Higgs and Technicolor with Higgs data
    Dr Haiying CAI (IPNL, Lyon)
    16/01/2015 09:53
    We focus on the possibility that the Higgs boson is a state which is either as a Pseudo Goldstone Boson of an effective Lagrangian description or as a composite state made of techini fermions. In this composite Higgs model, the symmetry breaking pattern is SU(4)/SP(4) and the light Higgs will further mix with a heavier techni-Higgs. We consider the constraints on the parameter space both from...

  5. 25. Light-by-light scattering with intact protons at the LHC: from Standard Model to New Physics
    Dr sylvain fichet (ICTP/SAIFR)
    16/01/2015 10:07
    We discuss the discovery potential of light-by-light scattering at the LHC, induced by the SM and by new exotic charged particles. Our simulation relies on intact proton detection in the planned forward detectors of CMS and ATLAS. The full four-photon amplitudes generated by any electrically charged particles of spins 1/2 and 1, including the SM processes involving loops of leptons, quarks and...

  6. 43. EFT analysis of New Physics searches: from neutrons to Higgses
    Martin Gonzalez-Alonso (IPN Lyon)
    16/01/2015 10:21
    EFTs are a useful tool to analyze and compare different New Physics searches. I'll discuss the interplay between low-energy beta decay experiments and LHC searches, the application to Higgs decay data and the limitations of the method when light new particles are present.
