| contents | 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 $\mathcal{O}(β)$ and $\mathcal{O}(β^2)$ 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. |
