Probing Polarized Gluon Distributions through Charmed Hadron Production in Polarized pp Collisions at BNL--RHIC Energy
Toshiyuki Morii, Kazumasa Ohkuma
Abstract
In order to extract information about behavior of polarized gluons in the nucleon, charmed hadron productions, i.e. D* meson and Lambdac baryon productions, are studied in polarized pp reactions at BNL-RHIC energy. For these processes, the spin correlation asymmetry DLL between the target proton and the produced charmed hadron, and its statistical sensitivity delta DLL are calculated. From analyses on these processes, we found that the pseudo-rapidity distribution of DLL in the limited transverse momentum region is quite effective for distinguishing the model of polarized gluons as well as the model of spin-dependent fragmentation functions.
