Open Heavy Flavor Production in Heavy Ion Collisions

Open Heavy Flavor Production in Heavy Ion Collisions

The interaction of heavy partons, charm and beauty, with the matter created in heavy ion collisions has been of great interest in recent years. Heavy partons were predicted to interact less strongly with the matter than light partons. In apparent contrast to these predictions, unexpectedly strong suppression of non-photonic electrons from heavy flavor decays has been seen. However, significant ...

Open heavy flavor production from light ion collisions at RHIC

PHENIX measures leptons at mid and forward rapidities and extracts leptons resulting from semi-leptonic decays of heavy quarks. We present PHENIX results related to heavy quark production, specifically the invariant cross section of the non-photonic single electrons produced at midrapidity in p+p and d+Au collisions at √ sNN = 200 GeV . The measured cross section for p+p collisions is compared ...

Heavy Flavor Production in Hadronic Collisions

On Open Charm Production in Heavy Ion Collisions

We update the calculation of c − c production in the initial stage of nucleus nucleus collisions and within quark gluon plasma, using the most recent and most accepted values for the ingredients, such as nuclear parton distributions, quark masses, couplings and fireball parameters. We find a large discrepancy in the charm yields, depending on the input choices. A global analysis of all the diff...

Heavy Quarks and Meson Production in Ultraperipheral Heavy Ion Collisions

In the last years, there has been a lot of interest in the description of electron-nucleus collisions at high energies. The results of current analysis show that future electronnucleus colliders at HERA and RHIC, probably could determine whether parton distributions saturate and constraint the behavior of the nuclear gluon distribution in the full kinematical range . However, until these collid...
