We discuss models where the Higgs boson of the electroweak standard model plays the role of the inflaton. We focus on the question of the violation of perturbative unitarity due to the coupling of the...
We show that a five dimensional Universal Extra Dimension model, compactified on a line
segment, is consistently formulated even when the gauge symmetry is broken solely by non-
zero Dirichlet bound...
For particle physicists analysing the first data from CERN’s Large Hadron Collider (LHC) in Geneva, it is the �4.3 bn question: is there a particle known as the Higgs, which endows all others with mas...
