PHASE TRANSITION(S) IN FINITE-DENSITY QCD

The Grand Canonical formalism is generally used in numerical simulatio ns of finite density QCD since it allows free mobility in the chemical potential mu. We show that special care has to be used in extracting numerical results to avoid dramatic rounding effects and spurious tran sition signals. If we analyze data correctly, with reasonable statisti cs, no signal of first order phase transition is present and results u sing the Glasgow prescription are practically coincident with the ones obtained using the modulus of the fermionic determinant.
