In this thesis we present several studies on the origin of masses at the LHC. First we study the indirect effects of new physics on the couplings of the recently discovered Higgs boson and on the ...

In this thesis we study the possibility that QCD breaks parity at high temperatures and densities, a scenario that may be tested in heavy ion collisions. We present two different approaches to this ...
