$\pi$-$J/\psi$ 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 ...

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

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 ...

Angular-ordered parton showers with medium-modified splitting functions

, 2009
Modified Altarelli-Parisi splitting functions were recenty proposed to model multi-parton radiation in a dense medium and describe jet quenching, one of most striking features of heavy-ion collisions.

Conversion of photons to dileptons in the Kroll-Wada and parton shower approaches

Journal of High Energy Physics
The study of dileptons in high-energy heavy-ion collisions provides critical insights into the properties of the quark-gluon plasma and the thermal radiation emitted throughout its evolution.

Momentum imbalance of isolated photon-tagged jet production at RHIC and LHC

, 2013
In collisions of ultra-relativistic nuclei, photon-tagged jets provide a unique opportunity to compare jet production and modification due to parton shower formation and propagation in strongly-interacting matter at vastly different center-of-mass ...

On parton showers and multi parton interaction

, 2016
In high energy hadron-hadron collisons (like for example at LHC) Drell Yan processes are important. For a precise determination of the inclusive crosssection higher order calculations must be taken into account. In the region of phase space near threshold (where soft gluon emission dominates) largedouble logarithmic corrections become important.

Phenomenology with unintegrated parton showers [PDF]

Proceedings of the 40th International Symposium on Multiparticle Dynamics, 2011
We introduce a backward evolution Monte Carlo algorithm implementation of the CCFM equation and present latest developments in phenomenology of hadron-hadron collisions for the Monte Carlo generator Cascade.

Differential $t\bar{t}$ Cross Section Measurements as a Function of Variables other than Kinematics

, 2016
An overview of cross section measurements as a function of jet multiplicities and jet kinematics in association with $t\bar{t}$ production is presented.
