✦ Synopsis

The relative angle correlation of intermediate mass fragments has been studied for p + Au collisions at 8.1 GeV. Strong suppression at the small angles is observed caused by IMF-IMF Coulomb repulsion. Experimental correlation function is compared to that obtained by the multibody Coulomb trajectory calculations with the various decay times τ of fragmenting system. The combined model, including the empirically modified intranuclear cascade followed by statistical multifragmentation, was used to generate starting conditions for these calculations. The model dependence of the results obtained has been carefully checked. The mean decay time of fragmenting system is found to be τ 70 fm/c.

Recent progress in full jet reconstruction in heavy-ion collisions at RHIC makes it a promising tool for the quantitative study of the QCD at high energy density. Measurements in d+Au collisions are important to disentangle initial state nuclear effects from medium-induced k T broadening and jet que

Measurements of event-by-event fluctuations of the mean transverse momentum in Pb-Au collisions at 40, 80, and 158 A GeV/c are presented. A significant excess of mean p T fluctuations at mid-rapidity is observed over the expectation from statistically independent particle emission. The results are s
