Lattice simulations for BSM scenarios
Prof. Luigi Del Debbio (University of Edinburgh)

The possibility of a composite Higgs boson is still viable in the light of the results obtained so far at the LHC, but a quantitative understanding of strong dynamics is necessary in order to develop a microscopic theory of a composite Higgs. Because of the difficulties in taming the nonperturbative dynamics of asymptotically-free gauge theories at low energies, phenomenological studies have relied mostly on effective field theory approaches, or large-N models. Lattice field theory allows studies of strongly-interacting dynamics to be performed by numerical simulations, and hence provide a complementary approach to study this problem. In this talk I will review the techniques that have been developed to study these problems, and the recent results obtained for models of BSM physics.
