Abstract

SU(2) lattice gauge theory with two Dirac species of light, adjoint fermions included in the dynamics is simulated at finite temperatures by use of the microcanonical algorithm. The theory contains two natural mass scales, the string tension for heavy, fundamental quarks and the chiral-symmetry-breaking scale of light, adjoint quarks. The two scales are found to be distinct. This result generalizes earlier results obtained in the quenched approximation and should encourage builders of hierarchal models.
