45. Implications of Higgs discovery and other recent data for SUSY

Both the ATLAS and the CMS experiments have discovered a Higgs boson with mass ~126 GeV while setting new stringent lower limits on superpartner masses. The LHCb collaboration has for the first time measured BR(B_s -> mu+ mu-). I will present some implications of these results for supersymmetry and discuss ensuing prospects for SUSY searches at the LHC and in dark matter experiments.

54. General Composite Higgs Models

We construct pseudo-Goldstone composite Higgs models that are not necessarily of moose-type and characterize the main properties these models should have in order to give rise to a Higgs mass at around 125 GeV. We assume the existence of relatively light and weakly coupled spin 1 and 1/2 resonances. In absence of a symmetry principle, we introduce the Minimal Higgs Potential (MHP) hypothesis:...

56. COMPOSITE TWO HIGGS DOUBLET MODELS

Carlos Savoy (CNRS)

Composite two Higgs doublet models, where the Higgs fields arise as composite pseudo Nambu-Goldstone modes from the breaking of global symmetries in a strong interacting sector, are described with emphasis on the crucial issues of anomalous contributions to the T parameter and to Flavor Changing Neutral Currents. The non linear Lagrangians of several models are explicitly derived and the...

Measurements of the Yukawa couplings of the recently discovered boson $h$ to fermion pairs will provide a new arena for studying flavor physics. We analyze the lessons that can be learned by measuring the $h$ decay rates into the charged lepton pairs, $\tau^+\tau^-$, $\mu^+\mu^-$ and $\tau^\pm\mu^\mp$. We demonstrate how this set of measurements can distinguish in principle between various...
