Abstract

We use a modified directed path algorithm to study the finite temperature chiral singularities of two color lattice QCD with staggered fermions at strong coupling. Our lattice calculations are done at a fixed finite temperature in the broken phase with a variety of different quark masses. We find that to the lowest order, the behavior of our observables, namely the condensates and the decay constants are all consistent with the predictions of the low energy effective theory of our model. We further notice that in order to see consistency, the quark masses used in our lattice calculations need to be quite small than typically used.
