Query: 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 jets is also
considered.
