Parton energy loss in Au+Au collisions at RHIC energies is studied by numerically solving the relativistic Boltzmann equation for the partons including $2 \leftrightarrow 2$ and $2 \to 2 + final state radiation$ collision processes. Final…

Heavy-ion collisions at the BNL-RHIC collider can probe whether gluon saturation effects in nuclei at small x have set in, or whether leading-twist perturbative estimates of particle production are still applicable. I discuss that soon to…

High $p_{\rm T}$ hadrons in the small systems of $d/^3$He+Au and $p$+Al/Au collisions have been measured at the midrapidity ($|\eta|<0.35$) as well as at the forward and backward rapidities ($1.2<|\eta|<2.4$) at $\sqrt{s_{NN}}$=200GeV. A…

We present recent results for heavy flavor and jets produced in $\sqrt{s_{NN}} = 200$ GeV p-p, d-Au, Cu-Cu and Au-Au collisions at at RHIC. We find J/$\psi$ production is suppressed in Au-Au, but high energy J/$\psi$ are not suppressed in…

When studying the initial state and evolution of the matter created in relativistic heavy ion collisions, high-pT direct photons are a powerful probe. They are created in initial hard processes and in parton fragmentation, and possibly in…
