On the dihadron angular correlations in forward pA collisions
Physics Letters B, 2018 Dihadron angular correlations in forward pA collisions have been considered as one of the most sensitive observables to the gluon saturation effects.

Parton shower matching and merging [PDF]
Proceedings of Corfu Summer Institute 2017 "Schools and Workshops on Elementary Particle Physics and Gravity" — PoS(CORFU2017), 2018 With Run-II of the LHC starting its final year of data-taking, high precision theoretical predictions through Monte-Carlo event generators whose uncertainties match that of the recorded data are of highest importance. This talk summarises the progress of the field and highlight a number of recent developments.

Measurement of parton shower observables with OPAL
EPJ Web of Conferences, 2016 A study of QCD coherence is presented based on a sample of about 397,000 e+e- hadronic annihilation events collected at √s = 91 GeV with the OPAL detector at LEP.

GR@PPA 2.9: radiation matching for simulating photon production processes in hadron collisions
, 2018 We release an event generator package, GR@PPA 2.9, for simulating the direct (single) photon and diphoton (double photon) production in hadron collisions.

Properties of Three-Body Decay Functions Derived with Time-Like Jet Calculus beyond Leading Order
, 2002 Three-body decay functions in time-like parton branching are calculated using the jet calculus to the next-to-leading logarithmic (NLL) order in perturbative quantum chromodynamics (QCD). The phase space contributions from each of the ladder diagrams and

Parton showers in leptoproduction events
Zeitschrift für Physik C Particles and Fields, 1988 We present a model that includes the production of arbitrarily many jets in lepton-hadron events, using the leading log formalism for parton shower evolution. The main problem encountered here, which has not previously been illuminated by studies ofe+e− annihilation or Drell-Yan/Z0/W± production, is the choice of kinematics in the space-like shower ...

Next-to-leading-logarithmic PanScales showers for deep inelastic scattering and vector boson fusion
Journal of High Energy PhysicsWe 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

$\pi$-$J/\psi$ Correlation and Elliptic Flow Parameter $v_2$ of Charmed Mesons at RHIC Energy
, 2011 We study the correlation between the trigger $\pi$ and the associated $J/\psi$ on near and away sides in Au+Au collisions at $\sqrt{s_{NN}}=200$ GeV. In the region of trigger momentum $p_t>4$ GeV/$c$, the $\pi$ spectrum is composed of thermal-shower and ...

Underlying event sensitive observables in Drell-Yan production using GENEVA
, 2016 We present an extension of the GENEVA Monte Carlo framework to include multiple parton interactions (MPI) provided by PYTHIA8. This allows us to obtain predictions for underlying-event sensitive measurements in Drell-Yan production, in conjunction with ...
