摘要We present the theoretical predictions up to QCD next-to-leading order for the cross section of high-mass electron--muon pair production at the Tevatron and at the Large Hadron Collider (LHC), considering only the dominant contributions from the third-generation sneutrino. The dependence of the renormalization and factorization scales on the total cross section, and the effects on the K-factor due to the uncertainty of parton distribution function are carefully investigated. By considering soft-gluon resummation effects to all orders in αs of leading logarithm, we present the transverse momentum distributions of the final eμ pair.
