We first use perturbative QCD theory to calculate the photon production cross section in nu- cleon - nucleon collisions at a center-of-mass energy of a few tens of GeV, taking into account the intrinsic parton transverse mo- mentum distribution and the next-to-leading-order contributions.

The contradiction between the quark spin structure of nucleon of the constituent quark model and the measured one in the polarized deep inelastic lepton nucleon scattering has been explained in detail.

簡要介紹了夸克的發(fā)現(xiàn)花蝴蝶免费高清在线视频观看、核子的夸克模型亚洲免费色视频，詳細(xì)討論了夸克模型中核子內(nèi)夸克自旋結(jié)構(gòu)和極化輕子-核子深度非彈散射測量出的夸克自旋結(jié)構(gòu)中的矛盾。

In the past years, the chiral SU(3) quark model has achieved success. In this model, the nonet pseudo-scalar meson exchanges and the nonet scalar meson exchanges are considered in describing the medium-and long-range parts of the interactions, and the one gluon exchange describe the short-range repulsion.

The calculations of nucleus-nucleus potential are carried out in the framework of double folding model with M3Y-Reid and M3Y-Paris effective nucleon-nucleon interactions. The exchange part of the interaction, which is taken to be of finite range and the density dependence of NN interaction, is accounted for in the folding procedure. The results are used as the real part of the optical potential for heavy ion scattering.
