Next-to-leading order predictions for Z gamma+jet and Z gamma gamma final states at the LHC
John M. Campbell, Heribertus B. Hartanto, Ciaran Williams
We present next-to-leading order predictions for final states containing leptons produced through the decay of a Z boson in association with either a photon and a jet, or a pair of…
Extending the Matrix Element Method to Next-to-Leading Order
John M. Campbell, Walter T. Giele, Ciaran Williams
We discuss the extension of the matrix element method (MEM) to Next-to-Leading Order (NLO) in perturbation theory. In particular we focus on the production of a Standard Model Higg…
The Matrix Element Method at Next-to-Leading Order
John M. Campbell, Walter T. Giele, Ciaran Williams
This paper presents an extension of the matrix element method to next-to-leading order in perturbation theory. To accomplish this we have developed a method to calculate next-to-le…
NLO Higgs boson production plus one and two jets using the POWHEG BOX, MadGraph4 and MCFM
John M. Campbell, R. Keith Ellis, Rikkert Frederix +3
We present a next-to-leading order calculation of Higgs boson production plus one and two jets via gluon fusion interfaced to shower Monte Carlo programs, implemented according to…
