Implementation of angularly ordered electroweak parton shower in Herwig 7

چکیده
We discuss the necessary steps for implementing an angularly ordered (AO) electroweak (EW) parton shower in Herwig 7 multi-purpose event generator. This includes calculating helicity-dependent quasi-collinear EW branching functions that correspond to full range of final-state shower, addition initial-state gauge vector boson radiations. The results are successfully embedded AO algorithm and have undergone a set comprehensive conclusive performance tests. Furthermore, we used this algorithm, alongside existing $QCD+QED$ predict angular distributions $W^{\pm}$ bosons LHC events with high transverse momentum jets. These compared against explicitly generated underlying as well ATLAS data show effectiveness newly implemented $QCD+QED+EW$ scheme.

Implementation of a medium-modified parton shower algorithm
We present a Monte Carlo implementation of medium-induced gluon radiation in the final-state branching process. Medium effects are introduced through an additive term in the splitting functions. We have implemented such modification within PYTHIA. We show the medium effects on the hump-backed plateau, and the transverse momentum and angular distributions with respect to the parent parton. As ex...
متن کاملAn improved Parton Shower algorithm in QED
An improved QED Parton Shower algorithm to calculate photonic radiative corrections to QED processes at flavour factories is described. We consider the possibility of performing photon generation in order to take into account also the effects due to interference between initial and final state radiation. Comparisons with exact order α results are shown and commented.
متن کاملMatrix-Element Corrections to Parton Shower Algorithms
We discuss two ways in which parton shower algorithms can be supplemented by matrix-element corrections to ensure the correct hard limit: by using complementary phase-space regions, or by modifying the shower itself. In the former case, existing algorithms are self-consistent only if the total correction is small. In the latter case, existing algorithms are never self-consistent, a problem that...
متن کاملA Parton Shower for High Energy Jets
We present a method to match the multi-parton states generated by the High Energy Jets Monte Carlo with parton showers generated by the ARIADNE program using the colour dipole model. The High Energy Jets program already includes a full resummation of soft divergences. Hence, in the matching it is important that the corresponding divergences in the parton shower are subtracted, keeping only the ...
متن کاملMatching matrix elements and parton showers with HERWIG and PYTHIA
We report on our exploration of matching matrix element calculations with the parton-shower models contained in the event generators HERWIG and PYTHIA. We describe results for e+e− collisions and for the hadroproduction of W bosons and DrellYan pairs. We compare methods based on (1) a strict implementation of ideas proposed by Catani et al., (2) a generalization based on using the internal Suda...
