Abstract: We derive a factorization theorem for the differential distributions ofelectroweak gauge bosons in Drell-Yan processes, valid at low transversemomentum, using the Soft-Collinear Effective Theory SCET. We present thenext-to-leading logarithmic NLL transverse momentum distribution for theZ-boson and find good agreement with Tevatron data collected by the CDF and D0collaborations. We also give predictions for the Higgs boson differentialdistributions at NLL based on a factorization theorem derived in earlier work.We derive formulae for all quantities needed to study low transverse momentumproduction of color-neutral particles within the effective theory. Thiseffective field theory approach is free of Landau poles and can be formulatedentirely in momentum space. Consequently, our results are free of theLandau-pole prescriptions necessary in the standard approach.
