Abstract: A bstract We investigate the collinear matching of transverse momentum dependent (TMD) distributions at large values of x , computing and resumming the leading large- x asymptotics for matching coefficients. The large- x resummation is done directly within TMD distributions, ensuring the process-independence of the result. The derived resummation formulas are valid for all TMD distributions (except the pretzelosity). Their application improves perturbative convergence, provides practical estimation for unknown higher-order contributions, and sets restrictions for the nonperturbative part of models. Using the known anomalous dimensions, resummation can reach N 3 LL, often exceeding the accuracy of known coefficient functions.
