Description

Jet-induced medium excitation and the resulting diffusion wake are essential components of jet-medium interactions in the Quark-Gluon Plasma (QGP). The modification of hadron chemistry, particularly the baryon-to-meson and strange-to-non-strange yield ratios, provides a unique probe of such medium excitations, as recently hinted at by experimental observations.
In this work, we present a comprehensive study of the chemical composition in both the near-side and away-side jet regions. We calculate the baryon-to-meson ($p/\pi$) and strange-to-non-strange ($K/\pi$) ratios correlated with quenched jets in Pb+Pb collisions at $\sqrt{s_{NN}} = 5.02~\mathrm{TeV}$.
Our results for the near-side hadron chemistry show good agreement with the experimental data. We further examine the $p/\pi$ and $K/\pi$ ratios on the away side in dijet events. We have also extended our study to $\gamma$-jet events.
