"Lattice study of gauge theory with multiple fermion representations"

Presented by Ethan Neil, University of Colorado, Boulder and RBRC

Thursday, May 4, 2017, 12:30 pm — Building 510, Room 2-160

"There is long-standing theoretical interest in the behavior of a strongly-coupled gauge theory in the presence of multiple fermions charged under different representations of the gauge group. In addition to the question of whether generation of dynamically separated scales will occur, such theories appear commonly in UV realizations of composite Higgs models with partially composite top quarks. I will present a first lattice study of SU(4) gauge theory with fermions in each of the two lowest-lying representations, discussing the finite-temperature phase structure and low-lying spectrum. Connections to BSM physics through a particular composite Higgs model will also be made."
