Effects of the large gluon polarization on $x g_{1}^{d} (x)$ and J/ $ψ$ productions at polarized ep and pp collisions

Abstract

The recent SMC data of $x g_{1}^{d} (x)$ are reproduced with the large polarized gluons. To study further the polarized gluon distribution in a proton, we calculate the spin--dependent differential cross section for J/ $ψ$ leptoproductions and the two--spin asymmetry for J/ $ψ$ hadroproductions. Its experimental implication is discussed.
