Comparative study of various algorithms for the merging of parton showers and matrix elements in hadronic collisions
We compare different procedures for combining fixed-order tree-level matrix-element generators with parton showers. We use the case of W-production at the Tevatron and the LHC to compare differentExpand
Event generation with
In this paper the current release of the Monte Carlo event generator Sherpa, version 1.1, is presented. Sherpa is a general-purpose tool for the simulation of particle colli- sions at high-energyExpand
NLO matrix elements and truncated showers
In this publication, an algorithm is presented that combines the ME+PS approach to merge sequences of tree-level matrix elements into inclusive event samples [1] with the Powheg method, whichExpand
QCD matrix elements + parton showers. The NLO case
A bstractWe present a process-independent technique to consistently combine next-to-leading order parton-level calculations of varying jet multiplicity and parton showers. Double counting is avoidedExpand
A critical appraisal of NLO+PS matching methods
A bstractIn this publication, uncertainties in and differences between the MC@NLO and POWHEG methods for matching next-to-leading order QCD calculations with parton showers are discussed.Expand
The midpoint between dipole and parton showers
We present a new parton-shower algorithm. Borrowing from the basic ideas of dipole cascades, the evolution variable is judiciously chosen as the transverse momentum in the soft limit. This leads to aExpand
Four-jet production at the Large Hadron Collider at next-to-leading order in QCD.
We present the cross sections for production of up to four jets at the Large Hadron Collider, at next-to-leading order in the QCD coupling. We use the BLACKHAT library in conjunction with SHERPA andExpand
Beyond standard model calculations with Sherpa
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 model information givenExpand
Introduction to parton-shower event generators
This lecture discusses the physics implemented by Monte Carlo event generators for hadron colliders. It details the construction of parton showers and the matching of parton showers to fixed-orderExpand
A proposal for a standard interface between Monte Carlo tools and one-loop programs
The Binoth Les Houches Accord is a proposal for a standard interface between Monte Carlo tools and one-loop matrix element programs for phenomenological predictions at the next-to-leading order level. Expand
