Production of Massive Color-Octet Vector Bosons at Next-to-Leading Order
R. Sekhar Chivukula, Arsham Farzinnia, Roshan Foadi +1
We report the first complete calculation of QCD corrections to the production of a massive color-octet vector boson. Our next-to-leading-order (NLO) calculation includes both virtu…
aMC@NLO predictions for Wjj production at the Tevatron
Rikkert Frederix, Stefano Frixione, Valentin Hirschi +3
We use aMC@NLO to predict the lv+ 2-jet cross section at the NLO accuracy in QCD matched to parton shower simulations. We find that the perturbative expansion is well behaved for a…
Four-lepton production at hadron colliders: aMC@NLO predictions with theoretical uncertainties
Rikkert Frederix, Stefano Frixione, Valentin Hirschi +3
We use aMC@NLO to study the production of four charged leptons at the LHC, performing parton showers with both HERWIG and Pythia6. Our underlying matrix element calculation feature…
Matched predictions for Higgs production via heavy-quark loops in the SM and beyond
Johan Alwall, Qiang Li, Fabio Maltoni
The main Higgs production channel at hadron colliders is gluon fusion via heavy-quark loops. We present the results of a fully exclusive simulation of gluon fusion Higgs production…
Vector boson fusion at NNLO in QCD: SM Higgs and beyond
Paolo Bolzoni, Fabio Maltoni, Sven-Olaf Moch +1
Weak vector boson fusion provides a unique channel to directly probe the mechanism of electroweak symmetry breaking at hadron colliders. We present a method that allows to calculat…
ALOHA: Automatic Libraries Of Helicity Amplitudes for Feynman diagram computations
Priscila de Aquino, William Link, Fabio Maltoni +2
We present an application that automatically writes the Helas library corresponding to the Feynman rules of any Lagrangian, renormalizable or not, in quantum field theory. The code…
