Transverse momentum dependent transversely polarized distributions at next-to-next-to-leading-order Gutiérrez Reyes, Daniel Scimemi, Ignazio Vladimirov, Alexey NLO Computations QCD Phenomenology Física-Modelos matemáticos Partículas Teoría de los quanta 2208 Nucleónica 2210.23 Teoría Cuántica We calculate the matching of the transversity and pretzelosity transverse momentum dependent distributions (TMD) on transversity collinear distribution at the next-to-next-to-leading order (NNLO). We find that the matching coefficient for pretzelosity distribution is zero, despite the matrix element for it is nontrivial. This result suggests that the pretzelosity matches a twist-4 distribution. The matching for transversity TMD distributions is provided for both parton distribution functions and fragmentation functions cases.
