We present the calculation of the next-to-leading-order QCD corrections to electroweak pp -> e(+)nu(e)mu(+)mu(-)jj and pp -> e(-)(v) over bar (e)mu(+)mu(-)jj production at the CERN LHC in the form of a fully flexible parton-level Monte Carlo program. The QCD corrections to the total cross sections are modest, changing the leading-order results by less than 10%. At the Born level, the shape of kinematic distributions can depend significantly on the choice of factorization scale. This theoretical uncertainty is strongly reduced by the inclusion of the next-to-leading-order QCD corrections.

Abstract
We present the calculation of the next-to-leading-order QCD corrections to electroweak pp -> e(+)nu(e)mu(+)mu(-)jj and pp -> e(-)(v) over bar (e)mu(+)mu(-)jj production at the CERN LHC in the form of a fully flexible parton-level Monte Carlo program. The QCD corrections to the total cross sections are modest, changing the leading-order results by less than 10%. At the Born level, the shape of kinematic distributions can depend significantly on the choice of factorization scale. This theoretical uncertainty is strongly reduced by the inclusion of the next-to-leading-order QCD corrections.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
