Abstract

A supersymmetric lattice gauge model is proposed. By using the effective Lagrangian method, phenomena at finite temperature are studied at the strong-coupling limit. The fermion-antifermion condensate and scalar-antiscalar condensate form, and at zero temperature they are related to each other by supersymmetry. For the zero-quark mass case, the fermion-antifermion condensate disappears at some temperature, and the chiral phase transition is second order. Turning on the quark mass smoothes out that phase transition. On the other hand, scalar-antiscalar condensate always has nonzero values, and it blows up at the extreme high temperature limit.
