Weak Gauge Boson Radiation in Parton Showers
نویسندگان
چکیده
The emission of W and Z gauge boson is included in a traditional QCD + QED shower. The unitarity of the shower algorithm links the real radiation of the weak gauge bosons to the negative weak virtual corrections. The shower evolution process leads to a competition between QCD, QED and weak radiation, and allows for W and Z boson production inside jets. Various effects on LHC physics are studied, both at low and high transverse momenta, and effects at higher-energy hadron colliders are outlined. ar X iv :1 40 1. 52 38 v1 [ he pph ] 2 1 Ja n 20 14

Matching NLO QCD and Parton Showers in Heavy Flavour Production∗
We apply the MC@NLO approach to the process of heavy flavour hadroproduction. MC@NLO is a method for matching next-to-leading order (NLO) QCD calculations and parton shower Monte Carlo (MC) simulations, with the following features: fully exclusive events are generated, with hadronisation according to the MC model; total rates are accurate to NLO; NLO results for distributions are recovered upon...
متن کاملTransversal momentum of the electroweak gauge boson and forward jets in high energy factorisation at the LHC Dissertation zur Erlangung des Doktorgrades
Fixed order perturbation theory is not able to describe the transversal momentum spectrum of a electro-weak gauge boson. It is needed to resum whole classes of enhanced logarithmic terms. Depending on the phase space region different classes of logarithmic terms can be important. There are different approaches to sum such logarithmic terms including evolution equations of parton density functio...
متن کاملTriple vector boson production through Higgs-strahlung with NLO multijet merging
Triple gauge boson hadroproduction, in particular the production of three W-bosons at the LHC, is considered at next-to leading order accuracy in QCD. The NLO matrix elements are combined with parton showers. Multijet merging is invoked such that NLO matrix elements with one additional jet are also included. The studies here incorporate both the signal and all relevant backgrounds for VH produc...

Physics and programming aspects are discussed for a Fortran 77 Monte Carlo program to simulate complete events in deep inelastic leptonnucleon scattering. The parton level interaction is based on the standard model electroweak cross sections, which are fully implemented in leading order for any lepton of arbitrary polarization, and di erent parametrizations of parton density functions can be us...

Stefan Höche, Ye Li, and Stefan Prestel SLAC National Accelerator Laboratory, Menlo Park, CA 94025, USA Deutsches Elektronen-Synchrotron, DESY, 22603 Hamburg, Germany We discuss how the UNLOPS scheme for matching NNLO calculations to parton showers can be applied to processes with large higher-order perturbative QCD corrections. We focus on Higgsboson production through gluon fusion as an examp...
