摘要:

本文考虑了在壳层上极化和非极化光子碰撞中重夸克对的产生,并以解析形式给出了QCD中次领先级全光子自旋$J_z=0, \pm 2$的全积分总截面.唯象学的应用包括$b\bar b$的产生,它代表了标准模型中质量希格斯玻色子产生的不可约背景,以及$t\bar t$的产生。

英文摘要:

We consider the production of heavy-quark pairs in the collisions of polarized and unpolarized on-shell photons and present, in analytic form, the fully integrated total cross sections for total photon spins $J_z=0, \pm 2$ at next-to-leading-order in QCD. Phenomenological applications include $b\bar b$ production, which represents an irreducible background to standard-model intermediate-mass Higgs-boson production, as well as $t\bar t$ production.
