Transverse-momentum-dependent quark splitting functions in kT-factorization: real contributions
Abstract
We calculate transverse momentum dependent quark splitting kernels Pgq and Pqq within kT-factorization, completing earlier results which concentrated on gluon splitting functions Pgg and Pqg. 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.
