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

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