WG6: Quark-Gluon Plasma & Multi Parton Interactions

The formalism of Baier-Dokshitzer-Mueller-Peigné-Schiff and Zakharov determines the modifications of parton splittings in the QCD plasma that arise from medium-induced gluon radiation. Here, we study medium-modifications of the gluon splitting into a quark--anti-quark pair in this BDMPS-Z formalism. We derive a compact path-integral formulation that resums effects from an arbitrary number of...

31. Constraining quark and gluon jet energy loss distributions in quark-gluon plasma using Bayesian inference

WG6: Quark-Gluon Plasma & Multi Parton Interactions

QCD factorization allows us to model the jet energy-loss in A-A collisions as a convolution between the jet cross section in p-p collisions and an energy loss distribution. Meanwhile, Bayesian inference provides a data-driven way of constraining the energy loss distribution parameterization. Only a few efforts have been made in this direction, and solely using untagged jets. However, gluon and...

100. Soft probes of QGP

WG6: Quark-Gluon Plasma & Multi Parton Interactions

By colliding heavy nuclei at ultrarelativistic energies in the Large Hadron Collider (LHC), the quark-gluon plasma (QGP) -- a hot and dense medium in which partons are deconfined -- is created. The properties of this new state of nuclear matter can be characterized, in particular, by studying low momentum (or "soft") particles (which constitue the majority of the created particles) and the...
