"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."
