次领先阶精度极化强子碰撞中强子加光子的产生

Hadron plus photon production in polarized hadronic collisions at next-to-leading order accuracy

Daniel de Florian, German F. R. Sborlini

摘要:

我们计算了伴随着对侧瞬发光子的强子产生的极化(和非极化)截面的次至首阶QCD修正。这个过程,正在研究RHIC,使我们能够重建部分子运动学实验测量变量。我们研究了重建的动量分数与真实部分子动量分数之间的相关性,在极化情况下,这可能使我们能够以更高的精度揭示自旋相关的胶子分布。

英文摘要:

We compute the next-to-leading order QCD corrections to the polarized (and unpolarized) cross sections for the production of a hadron accompanied by an opposite-side prompt photon. This process, being studied at RHIC, permits us to reconstruct partonic kinematics using experimentally measurable variables. We study the correlation between the reconstructed momentum fractions and the true partonic ones, which in the polarized case might allow us to reveal the spin-dependent gluon distribution with a higher precision.
