The Higgs Boson and New Physics at the TeV Scale
  In this Thesis two different parts can be distinguished. In the first one, after a review of the SM Higgs sector, I describe some scenarios for new physics such as Little Higgs and Supersymmetry and discuss our contributions in each of them. In the second part I focus on one of the most interesting experimental hints of new physics, the forward-backward asymmetry in top-pair production measured at the Tevatron, analyzing in detail its possible implications at the LHC.
