Why Don't We See the Hagedorn Mass Spectrum in the Experiments?

Abstract

The influence of medium dependent finite width of the QGP bags on their equation of state is analyzed on a basis of an exactly solvable model with the general mass-volume spectrum of these bags. It is arguing that the consistent statistical description of the QGP bags is achieved for the width proportional to the square root of their volume. The model allows us to estimate the minimal value of the QGP bags' width from the new lattice QCD data. The large width of the QGP bags not only explains the observed deficit in the number of hadronic resonances compared to the Hagedorn mass spectrum, but also clarifies the reason why the heavy/ large QGP bags cannot be directly observed in experiments as metastable states in a hadronic phase.
