Fisher's Zeros and Perturbative Series in Gluodynamics

Presenter: Yannick Meurice — The University of Iowa

A. Denbleyker, D. Du, Y. Meurice and A. Velytsky

We study the zeros of the partition function in the complex beta plane (Fisher's zeros) in SU(2) and SU(3) gluodynamics. We discuss their effects on the asymptotic behavior of the perturbative series for the average plaquette. We present new methods to infer the existence of these zeros in region where MC reweighting is not reliable.
