Abstract

Lattice QCD with staggered fermions can be formulated in dual variables to address the finite baryon density sign problem. In the past we have performed simulations in the strong coupling regime, including leading order gauge corrections. In order to vary the temperature for fixed β it was necessary to introduce a bare anisotropy. In this talk we will extend our work to include results from a non-perturbative determination of the physical anisotropy a_σ/a_τ= ξ(γ, β), which is necessary to unambiguously locate the critical end point and the first order line of the chiral transition.
