A new striking feature of hadron production in nuclear collisions is the large stopping of the participating nucleons in hadron–nucleus and nucleus–nucleus collisions. This enhanced baryon stopping can be understood introducing new diquark breaking mechanisms in multistring models of hadron production. Here we show, that similar diquark breaking mechanisms occur at high energy even in hadron–ha...

In the 1960’s-1980’s high quality secondary beams became available at proton synchrotrons of increasing energies (PS, AGS, IHEP, FNAL, SPS). The secondary charged hadron beams contained the six stable or quasi stable charged particles π, K, p, p. The main experimental lines of research were: i) total hadron–hadron (hh) cross section measurements at high energies (plab > 20 GeV/c); ii) elastic h...

Relativistic hydrodynamics is essential to our current understanding of nucleus-nucleus collisions at ultrarelativistic energies (current experiments at the Relativistic Heavy Ion Collider, forthcoming experiments at the CERN Large Hadron Collider). This is an introduction to relativistic hydrodynamics for graduate students. It includes a detailed derivation of the equations, and a description ...

With relation to the RHIC spin programwe research the polarization effects in elastic proton-proton scattering at small momentum transfer and in the diffraction dip region. The calculations take into account the Coulomb-hadron interference effects including the additional Coulomb-hadron phase. In particular we show the impact of the form of the hadron potential at large distances on the behavio...
