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.

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.

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.

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 ...

Recent development in parton shower multijet merging

, 2016
Higher order calculations are necessary to predict and describe measurements in high energy collider physics. In recent years multiple approaches to combine multiple next-to-leading (NLO) order corrections with parton showers had been presented.

Matching hadronization and perturbative evolution: the cluster model in light of infrared shower cutoff dependence

Journal of High Energy Physics
In the context of Monte Carlo (MC) generators with parton showers that have next-to-leading-logarithmic (NLL) precision, the cutoff Q 0 terminating the shower evolution should be viewed as an infrared factorization scale so that parameters or non ...
