Energy loss of quarks in deconfined matter at RHIC: photon-tagged jets, single electron and dilepton spectra from open charm

We report a first attempt
(i) to derive constraints on the energy loss of charm quarks in a deconfined medium from the recent PHENIX data of single-electron transverse momentum spectra and
(ii) to estimate the resulting suppression of dileptons from correlated semi-leptonic decays of open charmed mesons.
The momentum imbalance of photon-tagged light-quark jetsis also considered.
