Detection of a signal in one of the standard LHC Higgs search channels does not guarantee that the particle discovered is the Standard Model (SM) Higgs. In this talk I survey some general classes of alternatives and ways to tell them apart.
The CMS and ATLAS collaborations have performed detailed studies of the discovery potential for the Higgs boson in MSSM. Different benchmarks scenarios have been studied both for the CP-conserving case and for the CP-violating one. Results…

Searches for the standard model Higgs boson are reviewed from the 2 TeV run of the Tevatron with ~ 10 fb-1 of recorded data, and from the 7 and 8 TeV runs of the LHC, with ~ 5 and ~ 6 fb-1, respectively, i.e., until the July-2012 discovery…
At $\sqrt{s} = 7$ TeV, the standard model needs at least $10\, (fb)^{-1}$ integrated luminosity at LHC to make a definitive discovery of the Higgs boson. Using binary tetrahedral ($T^{'}$) discrete flavor symmetry, we discuss how the decay…
