Angular (azimuthal or polar) correlations between produced particles in high energy hadronic/nuclear collisions carry a wealth of information on the dynamics of the strong interactions in the novel regime where parton densities of the target hadron or nucleus are high. As such they probe a relatively unexplored region of QCD kinematic phase space. Here we consider azimuthal angular correlations between three jets produced in Deep Inelastic Scattering in the kinematics region corresponding to low xBjorken of the target and show that high gluon density effects in the target lead to a disappearance of the away-side peaks.

The Average Phase Space Density (APSD) of very high energy nuclear collisions at the total "freeze-out" temperature offers an indirect but convenient tool to assess the merit and worth of the pionisation models. We have attempted to apply here a specific multiple production model with a view to estimating the APSD of pions for a set of sulphur-induced ultrarelativistic heavy-ion collisions in a unified manner, to compare them finally with the experiment-based results of NA35 and NA44-groups at CERN and also with the calculational results based on the thermal model. The specific implications of the present approach have also been pointed out in the end.

According to the usual application of the sequential-suppression picture to the dynamics of heavy quarkonia in the hot medium formed in ultrarelativistic nuclear collisions, quark–antiquark pairs created in a given bound or unbound state remain in that same state as the medium evolves. We argue that this scenario implicitly assumes an adiabatic evolution of the quarkonia and we show that the validity of the adiabaticity assumption is questionable.
