Beyond Standard Model calculations with Sherpa
Stefan Höche, Silvan Kuttimalai, Steffen Schumann +1
We present a fully automated framework as part of the Sherpa event generator for the computation of tree-level cross sections in beyond Standard Model scenarios, making use of mode…
Soft evolution of multi-jet final states
Erik Gerwick, Stefan Hoeche, Simone Marzani +1
We present a new framework for computing resummed and matched distributions in processes with many hard QCD jets. The intricate color structure of soft gluon emission at large angl…
Universality in W+Multijet Production
Z. Bern, L. J. Dixon, F. Febres Cordero +5
We study -boson production accompanied by multiple jets at 7 TeV at the LHC. We study the jet-production ratio, of total cross sections for +- to +()-jet productio…
Higgs-boson production through gluon fusion at NNLO QCD with parton showers
Stefan Höche, Ye Li, Stefan Prestel
We discuss how the UN2LOPS scheme for matching NNLO calculations to parton showers can be applied to processes with large higher-order perturbative QCD corrections. We focus on Hig…
High multiplicity processes with BlackHat and Sherpa
Jeppe R. Andersen, Stephanie Bartle, Zvi Bern +7
In this contribution, we present an intermediate storage format for next-to-leading order (NLO) events and explain the advantages of presenting a NLO calculation in this format. We…
Drell-Yan lepton pair production at NNLO QCD with parton showers
Stefan Hoeche, Ye Li, Stefan Prestel
We present a simple approach to combine NNLO QCD calculations and parton showers, based on the UNLOPS technique. We apply the method to the computation of Drell-Yan lepton-pair pro…
