The Alaric parton shower for hadron colliders [PDF]

We introduce the Alaric parton shower for simulating QCD radiation at hadron colliders and present numerical results from an implementation in the event generator Sherpa. Alaric provides a consistent framework to quantify certain systematic uncertainties

Next-to-leading-logarithmic PanScales showers for deep inelastic scattering and vector boson fusion

Journal of High Energy Physics
We introduce the first family of parton showers that achieve next-to-leading logarithmic (NLL) accuracy for processes involving a t-channel exchange of a colour-singlet, and embed them in the PanScales framework. These showers are applicable to processes

Studying the infrared behaviour of improved logarithmic accuracy parton showers with Herwig

Journal of High Energy Physics
We have implemented two recently proposed dipole shower algorithms that have next-to-leading-logarithmic accuracy at leading colour in the Herwig event generator.

Matching hadronization and perturbative evolution: the cluster model in light of infrared shower cutoff dependence

Journal of High Energy Physics
In the context of Monte Carlo (MC) generators with parton showers that have next-to-leading-logarithmic (NLL) precision, the cutoff Q 0 terminating the shower evolution should be viewed as an infrared factorization scale so that parameters or non ...

Measurement of dijet production with a veto on additional central jet activity in pp collisions at √s = 7 TeV using the ATLAS detector

EPJ Web of Conferences, 2012
A measurement of jet activity in the rapidity interval bounded by a dijet system is performed using pp collisions at 7 TeV recorded by the ATLAS detector in 2010.

The KrkNLO Method for Parton Shower Matching

Acta Physica Polonica B Proceedings Supplement
The consistent combination of Next-to-Leading-Order (NLO) perturbative QCD with the logarithmic resummation provided by parton shower algorithms (‘NLO matching’) is an indispensable tool for LHC phenomenology. Two methods for achieving this have been widely adopted: Mc@Nlo and Powheg. We summarise a third method, KrkNLO, its implementation in Herwig 7,
