摘要：We study the location of the partition function zeros in the complex b plane (Fisher’s Zeros) for
SU(2) lattice gauge theory on L4 lattices. We discuss recent attempts to locate complex zeros for
L = 4 and 6. We compare results obtained using various polynomial approximations of the logarithm
of the density of states and a straightforwardMC reweighting. We conclude that the method
based on a combination of discrete Chebyshev orthogonality and patching plaquette distributions
at different b provides the more reliable estimates.
