Probing jet medium interaction with generalized projected energy correlators
Abstract
We study medium modifications to generalized projected energy correlators, referred to as ν-correlators, measured on jets in heavy-ion collisions. While the vacuum distributions of these correlators exhibit a characteristic 1/ν enhancement, we show that in a dense medium this behavior is regulated within both the BDMPS-Z and semi-classical approximations as ν→ 0. As a result, contributions from medium-induced emissions become parametrically suppressed relative to the vacuum baseline. We observe a similar trend in the simulated events generated with JEWEL. We find that while the large angle enhancement is qualitatively similar across different values of ν, the small angle distribution changes drastically between ν<1 and ν>1. This indicates that small angle modifications, primarily driven by jet energy loss, are imprinted differently across ν-correlators. In particular, for ν<1 the small angle enhancement is less prominent which suggests that these correlators may provide improved sensitivity to medium modifications in the large angle region.
