Charmed Hadron Production in Polarized pp Collisions
Abstract
To extract information about polarized gluons in the proton, production of charmed hadrons, in particular, c+ 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 c+. Those statistical sensitivities were also calculated under the condition of RHIC experiment. We found that the pseudo-rapidity distribution of ALL is promising for testing the model of polarized gluons in the proton and also the spin-dependent fragmentation model of a charm quark decaying into c+ baryon.
