Resonance production from jet fragmentation

TL;DR

This paper explores how short-lived resonances produced from jet fragmentation in heavy-ion collisions can reveal properties of the quark-gluon plasma, focusing on high-momentum resonances on the away-side of di-jets.

Contribution

It presents initial results on triggered hadron-resonance correlations in Cu+Cu collisions, highlighting the potential of resonance studies to probe medium effects.

Findings

High momentum resonances are significantly modified by the medium.

Resonance production from jet fragmentation can serve as a probe of the quark-gluon plasma.

Early produced resonances are more sensitive to medium effects.

Abstract

Short lived resonances are sensitive to the medium properties in heavy-ion collisions. Heavy hadrons have larger probability to be produced within the quark gluon plasma phase due to their short formation times. Therefore heavy mass resonances are more likely to be affected by the medium, and the identification of early produced resonances from jet fragmentation might be a viable option to study chirality. The high momentum resonances on the away-side of a triggered di-jet are likely to be the most modified by the partonic or early hadronic medium. We will discuss first results of triggered hadron-resonance correlations in Cu+Cu heavy ion collisions.
