Quasitransverse momentum dependent distributions at next-to-next-to-leading order Río, Óscar del Vladimirov, Alexey 539.1 Asymmetry Partons Gluons Partículas 2207 Física Atómica y Nuclear 2023 Descuento SCOAP The partons' transverse momentum can be explored with QCD lattice simulations by studying the quasitransverse-momentum-dependent parton distribution functions (qTMDPDFs), which are factorized in terms of physical TMDPDFs and soft factors in the limit of the large hadron's momentum. We present the next-to-next-to-leading order (NNLO) calculation of the coefficient function for this factorization. Together with already known expressions for anomalous dimensions, this result allows analysis of lattice data at NNLO perturbative accuracy.
