NLO QCD corrections to $pp\rightarrow e^+ν_eμ^+ν_μjj$ in vector-boson fusion at the LHC (1311.1232v1)

Published 5 Nov 2013 in hep-ph

Abstract: We report on studies of next-to-leading order (NLO) QCD corrections to the process $pp\rightarrow e+\nu_e\mu+\nu_\mu jj$ which is associated with vector-boson fusion (VBF) production of an intermediate $W+W+$ pair. The impact of s-channel diagrams and interference contributions in VBF kinematics is analyzed at leading order (LO) and found to be entirely negligible. The NLO corrections are around 5% of the LO cross section, and the scale dependence is reduced to about ~1%. We introduce a dynamic scale which improves the K factor in the high-energy tails of the distributions.
