T-μphase diagram of the chiral quark model from a large flavor number expansion
A. Jakovac, A. Patkos, Zs. Szep +1
The chiral phase boundary of strong matter is determined in the T-μplane from the chiral quark model, applying a non-perturbatively renormalised treatment, involving chains of pion…

Universal threshold enhancement
A. Patkos, Zs. Szep, P. Szepfalusy
By assuming certain analytic properties of the propagator, it is shown that universal features of the spectral function including threshold enhancement arise if a pole describing a…
