Abstract

We study the mass spectrum of mesons at high temperature in SU(2) gauge theory with two flavorsof Dirac fundamental fermions. Numerical simulations are carried out on anisotropic latticesusing Wilson fermions, with lattice parameters tuned so that Euclidean symmetry is restored atlow energy. We dete...
