Abstract We present our experimental data for relative isotopic yields of nuclear fragments in high energy proton-nucleus collisions. When nuclear fragmentation is assumed to be droplet formation in a system near the critical point, the relative isotopic yields of 60 nuclear fragments in the mass range 12⩽Af⩽31 can be described by a simple thermodynamic model.

Au collisions measured by the E895 Collaboration in the energy range from 2 to 8 AGeV at the Brookhaven AGS are presented. Longitudinal flow parameters derived using a thermal model including collective longitudinal expansion are extracted from these distributions. The results show an approximately linear increase in the longitudinal flow velocity,

Abstract We have examined charged multiplicities arising from p−p and p− p collisions over the range of center of mass energies, s , from 30 GeV to 1800 GeV. Results from Tevatron experiment E735 support the presence of double parton interactions. These processes can be seen to account for a large fraction of the increase in the non single diffraction inelastic cross section from energies of about 200 GeV to 1800 GeV.
