Jets in evolving matter within the opacity expansion approach

TL;DR

This paper extends the opacity expansion approach to include medium motion effects in jet-medium interactions, accounting for transverse fields and energy transfer, with applications to heavy-ion collisions and Deep Inelastic Scattering.

Contribution

It introduces sub-eikonal contributions to the opacity expansion, incorporating medium motion effects previously neglected in jet-medium interaction models.

Findings

Computed color fields including transverse components

Accounted for energy transfer between medium and jet

Applied approach to Deep Inelastic Scattering

Abstract

In a recent study [1] we have extended the opacity expansion approach to describe jet-medium interactions including medium motion effects in the context of heavy-ion collisions. We have computed color field of the in-medium sources, including the effects of the transverse field components and the energy transfer between the medium and jet. The corresponding contributions are sub-eikonal in nature, and were previously ignored in the literature. Here we discuss how our approach can be applied to describe the medium motion effects in the context of Deep Inelastic Scattering.
