Away-side asymmetry of jet correlation relative to the reaction plane: a sensitive probe for jet in-medium modifications.
We propose a new observable based on two-particle azimuth correlation to study the away-side medium response in midcentral Au+Au collisions. We argue that a left-right asymmetry may appear at the away side by selecting triggers separately in the left and right sides of the reaction plane. A simple model estimation suggests that the magnitude of such asymmetry could reach 30% with details depending on the medium response mechanisms. This asymmetry, if observed, can help to distinguish competing theoretical models.
