Abstract / Bemerkung
In order to study the QCD chiral critical point we investigate Binder Cumulants of the chiral condensate. The results were obtained from simulations of 3 and 2+1 flavors of standard staggered fermions and 3 flavors of p4 improved staggered fermions. The quark masses used are close to the physical quark mass. To extract the dependence on quark mass and chemical potential we apply a new reweighting technique based on a Taylor expansion of the action. The reweighting accuracy is ${\cal O}(m)$ for the standard and ${\cal O}(m^2)$, ${\cal O}(\mu^2)$ for the p4 action.
