چکیده
Effects of the large gluon polarization on xg d 1 (x) and J/ψ productions at polarized ep and pp collisions Abstract The recent SMC data of xg d 1 (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.

Associate J / ψ + γ Production : A Clean Probe of Unpolarized and Polarized Gluon Densities
Color-octet contributions to the associate J/ψ+γ are found to be negligible, compared to the ordinary color-singlet contribution. Within the color-singlet model the J/ψ + γ production in the leading order is possible only through gluon-gluon fusion process. Therefore, the associate J/ψ+γ production remains to be useful as a clean channel to probe the unpolarized and polarized gluon distribution...
متن کاملHow to probe the spin – dependent gluon distributions †
Two–spin asymmetries A π 0 LL are calculated for various types of spin–dependent gluon distributions. It is concluded that the E581/704 data on A π 0 LL do not necessarily rule out the large gluon polarization but restrict severely the x dependence of its distribution. Moreover, A J/ψ LL are calculated for the forthcoming test of spin–dependent gluon distributions. The advent of so–called " the...
متن کاملThe Spin Structure of Nucleons and Deep Inelastic Scatterings
Based on a simple model which is compatible with the idea of the static quark model and the parton model, the polarized structure functions of proton and deuteron, two-spin asymmetries of π in polarized pp reactions and inelastic J/ψ productions in polarized lepton-proton collisions are analyzed. In particular, an important role of polarized gluon distributions is pointed out.

Polarized heavy quarkonium productions in Z 0 decays are considered. We find that polarizations of the produced quarkonia are independent of that of the parent Z 0 provided that one considers the energy distribution or the total production rate. Produced J/ψ's via the color-octet and the color-singlet mechanisms are expected to be 19% and 29% longitudinally polarized, respectively. The energy d...

Exclusive vector meson photoproduction, pp → ppV and pp → ppV occurs with significant rates at hadron colliders. The reaction can be used to study the gluon distribution of protons. Vector mesons may be produced with either proton as a target; because of interference between the two production channels, the pT spectra of vector mesons produced in pp and pp collisions are quite different. Becaus...
