论文摘要
我们直接从在不同能量下测得的差分横截面的比较中直接提出了一种新型的柯林斯 - 传动核提取方法。使用此方法,我们分析了由级联事件发生器生成的伪数据,并在较大的横向距离范围内提取parton分支模型预测的Collins-Soper内核。可以对该过程进行少量修改,以将其用于DRELL-YAN和SIDIS过程的实际测量数据。
We present a novel method of extraction of the Collins-Soper kernel directly from the comparison of differential cross-sections measured at different energies. Using this method, we analyze the pseudo-data generated by the CASCADE event generator and extract the Collins-Soper kernel predicted by the parton-branching model in the wide range of transverse distances. The procedure can be applied, with minor modifications, to the real measured data for Drell-Yan and SIDIS processes.
