New Physics in the Top Sector at LHC

  • Leonardo Benucci
Conference paper


Since its discovery, the top quark has appeared to be a very special object. It is distinguished by its large mass (∼ 170GeV/c 2), that is intriguingly close to the scale of EW symmetry breaking, and a Yukawa coupling surprisingly close to one Open image in new window . Are these only accidents? Is the top mass generated by the Higgs mechanism as the SM predicts, or does it play a more fundamental role in the EWSB? How new physics could affect the top quark properties? Next generation colliders will certainly contribute to solve these questions.
