abstract
We compute total cross sections for various slepton pair production reactions in next-to-leading order QCD. For pbarp collisions at root S=2TeV, we find leading order cross sections to be enhanced by typically 35% to 40%. For pp collisions at root S=14TeV, the enhancement ranges from 25% to 35% depending on the mass of the sleptons. We comment upon the phenomenological implications of these results.
