We study resummation of transverse-momentum-related large logarithmsgenerated from soft-gluon radiations in soft-collinear effective field theory.The anomalous dimensions of the effective quark and gluon currents, animportant ingredient for the resummation, are calculated to two-loop order. theresult at next-to-leading-log reproduces that obtained using the standardmethod for deep-inelastic scattering, Drell-Yan process, and Higgs productionthrough gluon-gluon fusion. We comment on the extension of the calculation tonext-to-next-to-leading logarithms.
