Description
We examine the reliability of available methods to constrain the location
of the critical endpoint from lattice simulations. For this, we use
several lattice simulations. First, we reexamine the Fodor-Katz
critical endpoint estimate using the same staggered lattice with
modern methods. Second, we look at the compatibility of the
reweighting result with estimates of the convergence radius of the
Taylor expansion. Third, we look at fine
staggered lattices, calculate higher order fluctuations there, and
make estimates of the radius of convergence, now close to the
continuum limit. The talk should make it clearer how much one
can trust claims in the literature about the lattice excluding
regions of the phase diagram for the critical endpoint location.
