✦ Synopsis

We describe a high-statistics investigation of the critical behavior as the quark mass, m approaches the endpoint m, of the first-order line separating the chirally symmetric and asymmetric phases in 3-flavor QCD using the Binder cumulant intersection method. This method and the resulting value of m, is compared with an earlier study using extrapolation of screening masses to m,. These results are obtained on lattice volumes of 83 x 4, 163 x 4 and 323 x 4 using staggered fermion masses of 0.015, 0.02, 0.025, 0.03, 0.035, 0.04 and 0.045.

We determine the location of the second order endpoint of the line of first order chiral phase transition in 3-flavor QCD at vanishing chemical potential (pLg). Using Ferrenberg-Swendsen reweighting for two values of the quark mass we determine the p,-dependence of the transition line and locate the

A new algorithm for location of the critical points in general scalar fields is described. The new method has been developed as part of an on-going process to exploit the topologic analysis of general 3D scalar fields. Part of this process involves the use of topologic information to seed the critic
