Strangeness production in a constituent quark model
F. Becattini, G. Pettini
We develop a model to calculate strangeness production in both elementary and heavy ion collisions, within the framework of a statistical approach to hadronisation. Calculations ar…
Strange quark production in a statistical effective model
F. Becattini, G. Pettini
An effective model with constituent quarks as fundamental degrees of freedom is used to predict the relative strangeness production pattern in both high energy elementary and heavy…
Analytic Lyapunov exponents in a classical nonlinear field equation
Roberto Franzosi, Raoul Gatto, Giulio Pettini +1
It is shown that the nonlinear wave equation , which is the continuum limit of the Fermi-Pasta-Ulam (FPU) beta model,…
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…
