摘要：

We study the differential cross sections for electroweak gauge-boson and Higgs production at small and very small transverse-momentum q(T). Large logarithms are resummed using soft-collinear effective theory. The collinear anomaly generates a non-perturbative scale q(*), which protects the processes from receiving large long-distance hadronic contributions. A numerical comparison of our predictions with data on the transverse-momentum distribution in Z-boson production at the Tevatron and LHC is given.
