摘 要: | 利用微扰量子色动力学和部分子模型,研究了相对论质子-质子碰撞产生的大横动量光子.在微扰量子色动力学中,大横动量光子的产生源主要有康普顿散射、夸克-反夸克湮灭、胶子夸克单圈以及部分子散射末态的光子碎裂等.理论计算结果能够较好地解释各能区质子-质子碰撞产生的光子实验数据.

Abstract: | Based on the perturbative quantum chromodynamics and parton model,the large transverse momentum photon generated in the relativistic proton-proton collisions is researched.In the perturbative quantum chromodynamics,the large transverse momentum photons are produced from Compton scattering,quark anti-quark annihilation,gluon quark lap,and photon fragmentation of scattering final state of partons.Theoretical calculation results explain the experimental data of photon generated from proton-proton collisions in different ergoregions. |

Keywords: | large transverse momentum photon production perturbative quantum chromodynamics parton model |
