Numerical studies of composite Higgs models

Theories beyond the Standard Model describe the Higgs boson as a composite state in the spectrum of some new strongly-interacting dynamics. Lattice simulations allow us to obtain quantitative results about the nonperturbative regime of these theories, and can provide phenomenological insight for model building. This project will focus on a particular class of theories, namely gauge theories with fermions in multiple representations. We will develop Monte Carlo codes for simulating these theories, and characterize their phase diagram and continuum limit. Phenomenological informations will be extracted from the spectrum of bound states and pattern of symmetry-breaking, which will lead to the determination of the parameters that define the Higgs potential in the Standard Model. A close interaction with phenomenological studies in expected.
