The expressions for the cross sections in SNS model can be
transformed to Einsstein formula for fluctuations of macroscopic
parameters of thermodinamical systems which permits to determine the
temperature of hadronic medium inside the proton that is close to
the utmost Hagedorn temperature. The energy dependence of the
temperature predicts the emergence of negative temperature of
protons. This may be some indication of paramagnetic properties of
the quarc-gluon medium inside the proton.
