چکیده
To extract information about polarized gluon distribution in the proton, charmed hadron, actually Λc , productions at RHIC experiment are studied. We found that the spin correlation asymmetry between the initial proton and the produced Λc is enable us to distinguish parameterization models of polarized gluons. † Talk presented by K.

Probing Polarized Gluon Distributions through Charmed Hadron Production in Polarized pp Collisions at BNL–RHIC Energy
In order to extract information about behavior of polarized gluons in the nucleon, charmed hadron productions, i.e. D meson and Λ+c baryon productions, are studied in polarized pp reactions at BNL-RHIC energy. For these processes, the spin correlation asymmetry ALL between the target proton and the produced charmed hadron, and its statistical sensitivity δALL are calculated as functions of tran...
متن کاملCharmed Hadron Production in Polarized pp Reactions as a Probe of Polarized Gluons in the Proton†
To probe the behavior of polarized gluons in the proton, we propose the charmed hadron, such as Λ+c and D ∗, production in the forthcoming RHIC experiments. We found that the spin correlation between the target proton and the produced Λ+c baryon might be a good signal for testing models of the polarized gluon distribution in the proton. † Talk presented by K. Ohkuma at the XVI Particle and Nucl...
متن کاملStatistical hadronization of charm at SPS, RHIC and LHC
We study the production of charmonia and charmed hadrons for nucleus-nucleus collisions at SPS, RHIC, and LHC energies within the framework of the statistical hadronization model. Results from this model are compared to the observed centrality dependence of J/ψ production at SPS energy. We further provide predictions for the centrality dependence of the production of open and hidden charm meson...
متن کاملCharmonium and open charm production in nuclear collisions at SPS/FAIR energies and the possible influence of a hot hadronic medium
We provide predictions for charmonium and open charm production in nuclear collisions at SPS/FAIR energies within the framework of the statistical hadronization model. The increasing importance at lower energies of Λc production is demonstrated and provides a challenge for future experiments. We also demonstrate that, because of the large charm quark mass and the different timescales for charm ...

We study the production of charmonia and charmed hadrons in nucleus-nucleus collisions at SPS, RHIC, and LHC energies within the framework of the statistical hadronization model. Results from this model are compared to the measured yields and centrality dependence of J/ψ production at SPS and RHIC energies. We explore and contrast the centrality dependence of the production of mesons with open ...
