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...

Sparticle mass hierarchies will play an important role in the type of signatures that will be visible at the Large Hadron Collider. We analyze these hierarchies for the four lightest sparticles for a general class of supergravity unified models including nonuniversalities in the soft breaking sector. It is shown that out of nearly 104 possibilities of sparticle mass hierarchies, only a small nu...
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...
