Scaling of the charm cross-section and modification of charm pT spectra at RHIC
نویسنده
چکیده
Charm production from the direct reconstruction of D (D → Kπ up to 2 GeV/c) and indirect lepton measurements via charm semileptonic decays (c → e+X at 0.9<pT<5.0 GeV/c and c → μ + X at 0.17<pT<0.25 GeV/c) at sNN = 200 GeV Au+Au collisions are analyzed. The transverse momentum (pT ) spectra and the nuclear modification factors for D and for leptons from heavy flavor decays is presented. Scaling of charm cross-section with number of binary collisions at √ s NN = 200 GeV from d+Au to Au+Au collisions is reported.

Extract charm cross section from its semileptonic decay at RHIC
We propose a sensitive measurement of the charm total cross section at RHIC through muon identification from charm semileptonic decay at low transverse momentum (pT ). This can test the binary-collision scaling (Nbin) properties of the charm total cross section and be used to study if heavy-flavor quarks as a probe are produced exclusively at the initial impact. The effects of the form factor o...

متن کاملHeavy Flavor Production at STAR
We present measurements on D meson production via direct reconstruction of its hadronic decay channel D → Kπ in minimum bias d+Au and Au+Au collisions at √ sNN=200 GeV with pT up to ∼3 GeV/c. Non-photonic electron spectra from the charm semi-leptonic decays are analyzed from the same data set as well as in p+p collision at √ s=200 GeV using the STAR Time-of-Flight (TOF) and Barrel EMC (BEMC) de...
متن کاملIdentification of Bottom Contribution in Non-photonic Electron Spectra and v2 at RHIC
We present a study on the spectra for heavy flavor (charm and bottom) decayed electrons in 200 GeV p+p collisions and provide the relative contributions of charm and bottom hadrons from the PYTHIA calculations. The results suggest that the crossing point of the electron spectra from charm and bottom decays is above 7 GeV/c and bottom contribution is not dominant for electron pT < 3 GeV/c. The u...
متن کاملOpen Charm Production in Heavy Ion Collisions and the Color Glass Condensate
We consider the production of open charm in heavy ion collisions in the framework of the Color Glass Condensate. In the central rapidity region at RHIC, for the charm quark yield we expect Ncoll (number of collisions) scaling in the absence of final–state effects. At higher energies, or forward rapidities at RHIC, the saturation scale exceeds the charm quark mass; we find that this results in t...
