Angular-ordered parton showers with medium-modified splitting functions
نویسندگان
چکیده
Modified Altarelli–Parisi splitting functions were lately proposed to model multi-parton radiation in a dense medium and describe jet quenching, one of most striking features of heavy-ion collisions. We implement mediummodified splitting functions in the HERWIG parton shower algorithm, which satisfies the angular ordering prescription, and present a few partonlevel results, such as transverse momentum, angle and energy-fraction distributions, which exhibit remarkable medium-induced effects. We also comment on the comparison with respect to the results yielded by other implementations of medium-modified splitting functions in the framework of virtuality-ordered parton cascades.

A modified CKKW matrix element merging approach to angular-ordered parton showers
A modified version of the CKKW matrix element merging algorithm is presented, suitable for use in an angular-ordered parton shower, using truncated showers and forced splittings. The algorithm is implemented in the Herwig++ Monte Carlo event generator for the benchmark process e+e− → hadrons. Results are presented at parton and hadron levels, demonstrating a smooth merging between the matrix el...
متن کاملConstraining in-medium heavy-quark energy-loss mechanisms via angular correlations between heavy and light mesons
Two-particle correlations obtained from parton showers that pass the hot and dense medium of the quark gluon plasma (QGP) can be used as an alternative observable, in addition to the combination of the nuclear modification factor RAA and the elliptic flow v2, to study the mechanisms of in-medium heavy quark energy-loss. In particular, angular correlations represent a promising tool to distingui...
متن کاملAngular ordering and parton showers for non-global QCD observables
We study the mismatch between a full calculation of non-global singlelogarithms in the large-Nc limit and an approximation based on free azimuthal averaging, and the consequent angular-ordered pattern of soft gluon radiation in QCD. We compare the results obtained in either case to those obtained from the parton showers in the Monte Carlo event generators HERWIG and PYTHIA, with the aim of asse...
متن کاملImplementation 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 کاملPolarized Antenna Splitting Functions
We consider parton showers based on radiation from QCD dipoles or ‘antennae’. These showers are built from 2→ 3 parton splitting processes. The question then arises of what functions replace the Altarelli-Parisi splitting functions in this approach. We give a detailed answer to this question, applicable to antenna showers in which partons carry definite helicity, and to both initialand final-st...
