Transverse-momentum-dependent quark splitting functions in $k_T$-factorization: real contributions
arXiv:1511.08439 · doi:10.1007/JHEP01(2016)181
Abstract
We calculate transverse momentum dependent quark splitting kernels $P_{gq}$ and $P_{qq}$ within $k_T$-factorization, completing earlier results which concentrated on gluon splitting functions $P_{gg}$ and $P_{qg}$. The complete set of splitting kernels is an essential requirement for the formulation of a complete set of evolution equations for transverse momentum dependent parton distribution functions and the development of corresponding parton shower algorithms.
