Abstract

We compute the resummed hadronic transverse energy (E T ) distribution due to initial-state QCD radiation in vector boson and Higgs boson production at hadron colliders. The resummed exponent, parton distributions and coefficient functions are treated consistently to next-to-leading order. The results are matched to fixed-order calculations at large E T and compared with parton-shower Monte Carlo predictions at Tevatron and LHC energies.
