论文摘要
最近已经研究了QCD进化方程的Parton分支解决方案,以构建共线和横向动量依赖(TMD)Parton分布。在这种形式主义中,引入了软绿色的分辨率量表,以分离可分离和不可辨别的分支,并考虑了软绿色的相干效应。在本次演讲中,显示了与高精度深度非弹性散射(DIS)结构函数测量结果的结果,包括首次在强耦合中,动态量表的效果,即近代级别的分支依赖性,分辨率尺度(NLO)精度。
Parton branching solutions of QCD evolution equations have recently been studied to construct both collinear and transverse momentum dependent (TMD) parton distributions. In this formalism, a soft-gluon resolution scale is introduced to separate resolvable and non-resolvable branchings, and to take into account soft-gluon coherence effects. In this talk, results of fits to the high precision deep inelastic scattering (DIS) structure function measurements are shown including for the first time the effects of dynamical, i.e. branching-scale dependent, resolution scales at Next-to-Leading-Order (NLO) accuracy in the strong coupling.
