NLO corrections to processes with electroweak bosons at hadron colliders
2015
For many processes with electroweak bosons in the final state, next-to-leading order QCD and, in some cases, electroweak corrections have been calculated for differential cross sections at hadron colliders. The calculational techniques and some phenomenological implications are reviewed in this contribution. Processes discussed include vector boson fusion and vector boson scattering, production of two and three electroweak bosons, potentially with jets, (VV j, VV jj and VVV events) and some Higgs production processes. All QCD corrections are implemented in the publicly available VBFNLO program package.
Next-to-leading order QCD corrections toW+W+andW−W−production in association with two jets
2014
We present a study of ${W}^{+}{W}^{+}jj$ and ${W}^{\ensuremath{-}}{W}^{\ensuremath{-}}jj$ production including leptonic decays in hadron-hadron collisions. The full electroweak and QCD induced contributions and their interferences are calculated at leading order. We find that, for inclusive cuts, the interference effects can be large if the jets are produced with large transverse momentum where, however, the production rate is suppressed. We also discuss the vector-boson-fusion cuts and show the validity of the vector-boson-fusion approximation. The next-to-leading order QCD corrections to the QCD-induced channels are also calculated. Compared to the previous calculation, we allow the inter…
QCD Induced Di-boson Production in Association with Two Jets at NLO QCD
2016
We discuss results for di-boson plus two jets production processes at the LHC at NLO QCD. Issues related to the scale choice are reviewed. We focus on the distributions of the invariant mass and rapidity separation of the two hardest jets and show, for $W^\pm \gamma jj$ and $Z\gamma jj$ production, how the contribution from the radiative decays of the massive gauge bosons can be significantly reduced.
WZ Production in Association with Two Jets at Next-to-Leading Order in QCD
2013
We report on the calculation of W-+/- Zjj production with leptonic decays at hadron-hadron colliders at next-to-leading order in QCD. These processes are important both to test the quartic gauge couplings of the standard model and because they constitute relevant backgrounds to beyond standard model physics searches. Our results show that the next-to-leading order corrections reduce significantly the scale uncertainties and have a nontrivial phase space dependence.
