Transverse momentum dependent transversely polarized distributions at next-to-next-to-leading-order

Gutiérrez Reyes, DanielScimemi, IgnazioVladimirov, Alexey2023-06-172023-06-172018-06-301029-847910.1007/JHEP07(2018)172https://hdl.handle.net/20.500.14352/12869We 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.engAtribución 3.0 Españahttps://creativecommons.org/licenses/by/3.0/es/Transverse momentum dependent transversely polarized distributions at next-to-next-to-leading-orderjournal articlehttps://doi.org/10.1007/JHEP07%282018%29172open accessNLO ComputationsQCD PhenomenologyFísica-Modelos matemáticosPartículasTeoría de los quanta2208 Nucleónica2210.23 Teoría Cuántica
