  1. 55. Spontaneous symmetry breaking in three-Higgs-doublet S3-symmetric models
    Margarida Nesbitt Rebelo (Centro de F\'isica Te\'orica de Part\'iculas -- CFTP and Dept de F\' \i sica Instituto Superior T\'ecnico -- IST, Universidade de Lisboa (UL))

    Plenary talk

    The talk will summarise work done by the author and collaborators consisting of a detailed study of the possible vacua in models with three Higgs doublets with S3 symmetry and without explicit CP violation. Different vacua require special regions of the parameter space which were analysed in our work. We establish the possibility of spontaneous CP violation in this framework and we also show...

  2. 13. On the Higgs self-coupling modifications
    Dr Ramona Groeber (IPPP Durham)
    18/04/2017, 17:16
    Plenary talk

    A determination of the Higgs self-coupling allows the reconstruction of the Higgs potential. In this talk I will discuss which kind of deviations in the trilinear Higgs self-coupling can be expected taking into account theoretical arguments and indirect constraints.

  3. 24. Controlled FCNC in Two Higgs Doublet Models
    Gustavo Branco (Technical University of Lisbon)
    18/04/2017, 17:39
    Plenary talk

    We analyse a class of Two Higgs Doublet Models (2HDM) where there are Flavour Changing
    Neutral Currents ( FCNC ) at tree level, but with their strength under control. We present
    a specific generalisation of BGL models in the context of 2HDM where there are FCNC both in the up and down sectors. Implications for baryogenesis are also analysed.

  4. 22. Assessing Higgs self coupling
    Christophe Grojean (DESY (Hamburg) and Humboldt University (Berlin))
    19/04/2017, 16:30
    Plenary talk

    I'll review the constraints that can be inferred on Higgs self-coupling from double Higgs production as well as from differential distributions in single Higgs processes. I'll discuss the impact of possible large deviations of the Higgs self-coupling on the determination of the single Higgs couplings

  5. 51. The energy and accuracy frontier
    Andrea Wulzer (CERN)
    19/04/2017, 16:53
    Plenary talk

    The large amount of data collected at the LHC and at its High-Luminosity extension will allow for accurate measurements of TeV-scale scattering processes that display enhanced indirect sensitivity to multi-TeV scale new physics. The power of those ``reasonably accurate and highly energetic’’ processes in probing heavy new physics is illustrated by showing that high-energy neutral and charged...

  6. 35. Higgs Sector of the Left-Right Symmetric Theory
    Dr Alessio Maiezza (IRB)
    19/04/2017, 17:16
    Plenary talk

    We perform an in-depth analysis of the Higgs sector in the Minimal Left-Right Symmetric Model and compute the scalar mass spectrum and associated mixings in the whole parametric space. A focus on the cubic potential couplings is provided in terms of the physical states and in the light of the (potentially large) quantum corrections. Then the deviations from the Standard Model prediction of the...
