Color Decoherence in In-Medium QCD Cascades

TL;DR

This paper investigates how quantum coherence effects, like angular ordering in QCD cascades, are affected when disrupted in the hot medium produced by ultrarelativistic heavy ion collisions.

Contribution

It provides a theoretical analysis of decoherence effects on QCD cascades in a quark-gluon plasma environment.

Findings

Quantum coherence effects are disrupted in the hot medium.

Angular ordering is affected by medium interactions.

Implications for jet quenching and particle correlations.

Abstract

The talk, based on \cite{LN10}, analyzes the consequences of the assumption that the effects of quantum coherence and the resulting angular ordering in QCD cascades are disrupted within the hot fireball created in ultrarelativistic heavy ion collisions.
