Azimuthal angle two particle correlations have been shown to be a powerful probe for extracting novel features of jet induced correlations produced in Au+Au collisions at RHIC. At intermediate $p_T$, 2-5GeV/c, the jets have been shown to be…

QCD color coherence phenomena, like angular ordering, can be studied by looking at jet fragmentation. As the jet is fragmenting, it is expected to go through two different phases. First, there is QCD branching that is calculable in…
Medium effects on charged-particle production are studied using three analysis techniques. We find angular collinearity and number correlations on $p_t$ at moderate $p_t<3$ GeV/$c$. In this $p_t$ range abundant multiplicities enable…
