To extract information about polarized gluon distribution in the proton, charmed hadron, actually [Formula: see text], productions at RHIC experiment are studied. We found that the spin correlation asymmetry between the initial proton and the produced [Formula: see text] is enable us to distinguish parameterization models of polarized gluons.

Polarized Gluon

Polarized parton distribution functions are determined by a χ2 analysis of polarized deep inelastic experimental data. In this paper, uncertainty of obtained distribution functions is investigated by a Hessian method. We find that the uncertainty of the polarized gluon distribution is fairly large. Then, we estimate the gluon uncertainty by including the fake data which are generated from prompt photon process at RHIC. We observed that the uncertainty could be reduced with these data.
