Order (αs2) QCD corrections to inclusive jet production in deep inelastic scattering

Mostrar todas las versiones(2)

We analyze the order αs2 corrections to the single inclusive jet cross section in lepton-nucleon deep inelastic scattering. The full calculation is done analytically, in the small cone approximation, obtaining finite NLO partonic level cross sections for these processes. A detailed study of the diff...
