Abstract

The strong coupling expansion for staggered fermions allows for Monte Carlo simulations using a dual representation. It has a mild sign problem for low values of the inverse gauge coupling β, hence the phase diagram in the full μ_B - T plane can be evaluated. We have extended this framework to include O(β) and O(β²) corrections, by mapping the degrees of freedom to a vertex model. We present results on the β-dependence of the chiral critical point from those simulations.
