Content
We study the phase structure of SU(4) gauge theory with dynamical quarks in both the fundamental and two-index antisymmetric representations. Such "multi-representation" theories have been speculated to exhibit separated phase transitions, but we determine from lattice results that the chiral transitions occur simultaneously with each other and with the confinement transition. We investigate the order of the combined phase transition in various limits of the theory, and compare to theoretical expectations based on chiral symmetry.
