script O sign(α<inf>s</inf>2) QCD corrections to the electroproduction of hadrons with high transverse momentum

Mostrar todas las versiones(2)

We compute the order α<inf>s</inf>2 corrections to the one particle inclusive electroproduction cross section of hadrons with nonvanishing transverse momentum. We perform the full calculation analytically, and obtain the expression of the factorized (finite) cross section at this order....
