Charmed Hadron Production at RHIC†
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. OHKUMA at 3rd Circum-Pan-Pacific Symposium on “High Energy Spi...
متن کاملCharmed Hadron Production in Polarized pp Collisions†
To extract information about polarized gluons in the proton, production of charmed hadrons, in particular, Λc baryon in pp collisions was studied. We calculated the transverse momentum distribution and the pseudo-rapidity distribution of the spin correlation asymmetry ALL between the initial proton and the produced Λc . Those statistical sensitivities were also calculated under the condition of...
متن کاملCharmed Hadron Interactions
We compute the scattering lengths of charmed mesons and charmonia scattering with light hadrons in full QCD. We use Fermilab formulation for the charm quark and domain-wall fermions for the light quarks and staggered sea quarks. Four different light-quark masses are used to extrapolate to the physical point. The charmed baryon spectrum is also presented.
متن کاملCharmed Hadron Spectroscopy from Focus
With very accurate measurements of the parameters of the ground state charmed mesons, interest has shifted to the array of excited charm meson states, especially with the interesting discoveries of the last year in the Ds sector. In the limit of infinite quark masses, D mesons may be treated as a “hydrogen atom” type object where the heavy quark does not contribute to the orbital degrees of fre...
متن کاملCharmed hadron signals of partonic medium
We present a short review of our results on the collectivity and the suppression pattern of charmed mesons in heavy-ion collisions based on the microscopic Hadron-String Dynamics (HSD) transport approach for different scenarios of charm interactions with the surrounding matter – the ‘comover’ dissociation by mesons with further recreation byD−D̄ channels and ‘pre-hadronic’ interaction scenarios....
