The numerical simulation of QCD at nite baryonic density is made difcult 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.

Abstract
The numerical simulation of QCD at nite baryonic density is made difcult 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.File in questo prodotto:
