Multijet events and parton showers [PDF]

open access: yesJournal of Physics G: Nuclear and Particle Physics, 1999
We propose a general approach for the description of multijet events in the framework of QCD event generators. We introduce a new algorithm to match parton showers and arbitrary matrix elements for the production of any number of jets via the strong or electroweak interaction. We developped a new parton cascade code capable to deal with multijet events

Measurements of the production cross section of a Z boson in association with jets in pp collisions at root s=13 TeV with the ATLAS detector [PDF]

open access: yes, 2014
Measurements of the production cross section of a Z boson in association with jets in proton–proton collisions at √s = 13 TeV are presented, using data corresponding to an integrated luminosity of 3.16 fb−1 collected by the ATLAS experiment at the ...

T‐Odd Anomalous Interactions of the Top‐Quark at the Large Hadron Collider

open access: yesAdvances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
We study the effects of T‐odd interactions of top‐quark via the pair production of the top‐quark in the semileptonic detection modes at the Large Hadron Collider by means of the T‐odd observables constructed through the momenta of the observed decay products of the top (and anti‐top)‐quark for a wide range of CP‐violating scale Λ.

The Physics Case for an Electron‐Muon Collider

open access: yesAdvances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
An electron‐muon collider with an asymmetric collision profile targeting multi‐ab-1 integrated luminosity is proposed. This novel collider, operating at collision energies of, e.g., 20–200 GeV, 50–1000 GeV, and 100–3000 GeV, would be able to probe charged lepton flavor violation and measure Higgs boson properties precisely. The collision of an electron

Cutoff dependence of the thrust peak position in the dipole shower

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We analyse the dependence of the peak position of the thrust distribution on the cutoff value in the Nagy–Soper dipole shower. We compare the outcome of the parton shower simulations to a relation of the dependence from an analytic computation, derived ...

Event Shape and Multiplicity Dependence of Freeze‐Out Scenario and System Thermodynamics in Proton+Proton Collisions at s=13 TeV Using PYTHIA8

open access: yesAdvances in High Energy Physics, Volume 2021, Issue 1, 2021., 2021
Recent observations of QGP‐like conditions in high‐multiplicity pp collisions from ALICE experiment at the LHC warrant an introspection whether to use pp collisions as a baseline measurement to characterize heavy‐ion collisions for the possible formation of a Quark‐Gluon Plasma.

Subleading Nc improved parton showers [PDF]

open access: yesJournal of High Energy Physics, 2012
Abstract We describe an algorithm for improving subsequent parton shower emissions by full SU(3) color correlations in the framework of a dipole-type shower. As a proof of concept, we present results from the first implementation of such an algorithm for a final state shower.

Combining single and double parton scatterings in a parton shower [PDF]

open access: yesJournal of High Energy Physics, 2020
Abstract Double parton scattering (DPS) processes in which there is a perturbative “1 → 2” splitting in both protons overlap with loop corrections to single parton scattering (SPS). Any fundamental theoretical treatment of DPS needs to address this double-counting issue.

Reweighting parton showers

open access: yesPhysical Review D, 2016
We report on the possibility of reweighting parton-shower Monte Carlo predictions for scale variations in the parton-shower algorithm. The method is based on a generalization of the Sudakov veto algorithm. We demonstrate the feasibility of this approach using example physical distributions.

HERWIG 6: an event generator for Hadron emission reactions with interfering gluons (including supersymmetric processes) [PDF]

open access: yes, 2000
HERWIG is a general-purpose Monte Carlo event generator, which includes the simulation of hard lepton-lepton, lepton-hadron and hadron-hadron scattering and soft hadron-hadron collisions in one package. It uses the parton-shower approach for initial- and
