Analytic continuation of the phase of the fermionic determinant.

Presenter: Simone Conradi — Dipartimento di Fisica Genova

Simone Conradi, Massimo D'Elia

The numerical simulation of QCD at finite baryonic density is made difficult by the complex nature of the fermionic determinant. We study the severeness of the problem as a function of the chemical potential by determining the average phase factor of the determinant at imaginary chemical potentials.
