论文摘要
如果两个观察到的部分之间的距离很小,则可以从一个parton分为两部分的双扰动分裂计算双parton分布。我们开发了在此计算中考虑Quark质量效应的方案,并在强耦合中以领先顺序进行数值研究。此外,我们详细研究了包括夸克质量效应的拆分内核的临近顺序校正的结构。
Double parton distributions can be computed from the perturbative splitting of one parton into two if the distance between the two observed partons is small. We develop schemes to take into account quark mass effects in this computation, and we study these schemes numerically at leading order in the strong coupling. Furthermore, we investigate in detail the structure of the next-to-leading order corrections to the splitting kernels that include quark mass effects.
