Title: Overview of Charm Physics at RHIC

Abstract

Heavy-quark production provides a sensitive probe of the gluon structure of nucleons and its modication in nuclei. It is also a key probe of the hot-dense matter created in heavy-ion collisions. We will discuss the physics issues involved, as seen in quarkonia and open heavy-quark production, starting with those observed in proton-proton collisions. Then cold nuclear matter effects on heavy-quark production including shadowing, gluon saturation, energy loss and absorption will be reviewed in the context of recent proton-nucleus and deuteron-nucleus measurements. Next we survey the most recent measurements of open-charm and, J/{psi}s in heavy-ion collisions at RHIC and their interpretation. We discuss the high-pT suppression and flow of open charm in terms of energy loss and thermalization and, for J/{psi}, contrast explanations in terms of screening in a deconfined medium vs. recombination models.

  • The results from data taken during the last several years at the Relativistic Heavy-Ion Collider (RHIC) will be reviewed in the paper. Several selected topics that further our understanding of constituent quark scaling, jet quenching and color screening effect of heavy quarkonia in the hot dense medium will be presented. Detector upgrades will further probe the properties of Quark Gluon Plasma. Future measurements with upgraded detectors will be presented. The discovery perspectives from future measurements will also be discussed.
  • In Spiring 2005, RHIC successfully completed its first long data collection run with polarized proton beams. PHENIX accumulated ten fold larger statistics with higher polarization than the previous spin physics run in 2003. This contribution will introduce the RHTC-PHENIX experiment and present our recent results.
  • The author presents results for the rapidity and transverse momentum distributions of inclusive charm production in heavy-ion collisions at RHIC and LHC energies. These calculations include the next-to-leading order, O({alpha}{sub s}{sup e}) radiative corrections and the nuclear shadowing effect. Using these calculations, the author determined the effective (in-medium) K-factor for thr differential and total charm cross sections. He found that this K-factor has a rapidity and a transverse momentum dependence. He found the fraction of central and inelastic events that contain at least one charm quark pair at RHIC and LHC energies. The author discusses all of the theoretical uncertaintiesmore » that appear in his calculations. In particular, he shows that the different extrapolations of gluon densities in a nucleon and in a nucleus to the low-x region can introduce large theoretical uncertainties in the calculation.« less
  • We make up-to-date QCD predictions for open charm and bottom production at RHIC in nucleon-nucleon collisions at {radical}S = 200 GeV. We also calculate the electron spectrum resulting from heavy flavor decays to allow direct comparison to the data. A rigorous benchmark, including the theoretical uncertainties, is established against which nuclear collision data can be compared to obtain evidence for nuclear effects.
  • The complete understanding of the basic constituents of hadrons and the hadronic dynamics at high energies are two of the main challenges for the theory of strong interactions. In particular, the existence of intrinsic heavy quark components in the hadron wave function must be confirmed (or disproved). In this paper we propose a new mechanism for the production of D-mesons at forward rapidities based on the Color Glass Condensate (CGC) formalism and demonstrate that the resulting transverse momentum spectra are strongly dependent on the behavior of the charm distribution at large Bjorken x. Our results show clearly that the hypothesismore » of intrinsic charm can be tested in pp and p(d)A collisions at RHIC and LHC.« less
