Title: Probing jet splitting and energy loss via groomed jets in relativistic heavy-ion collisions

Abstract

The nuclear modification of groomed jet splitting in relativistic heavy-ion collisions at RHIC and the LHC is studied based on higher twist jet energy loss formalism. Assuming coherent energy loss for two subjets, we find a non-monotonic dependence on jet energy for the nuclear modification of jet splitting function, which provides a good description of CMS and STAR groomed jet measurements. In contrast, the assumption of independent energy loss for two subjets cannot explain the observed nuclear modification pattern for groomed jet splitting.
