Pseudoscalar and scalar meson masses at finite temperature
A. Barducci, R. Casalbuoni, R. Gatto +2
The composite operator formalism is applied to QCD at finite temperature to calculate the masses of scalar and pseudoscalar mesons. In particular the ratio of the sigma mass to the…

Corrections to the Pagels-Stokar Formula for f_π
A. Barducci, R. Casalbuoni, R. Gatto +2
Within the composite operator formalism we derive a formula for the pion decay constant , as defined directly from the residue at the pion pole of the meson propagator, rather…

Discontinuity Theorem for First Order Phase Transitions. Implications for QCD
A. Barducci, R. Casalbuoni, G. Pettini +1
A first order phase transition leading to deconfinement and chiral restoration is a likely possibility for QCD, at least in some region of the temperature-density plane. A signal f…
