Abstract
We study the nuclear modification of the splitting function of groomed jets in relativistic heavy-ion collisions within the higher twist formalism. With the assumption of coherent energy loss of the two prongs, we find a non-monotonic dependence on jet energy for the nuclear modification of the jet splitting function, and provide a simultaneous description of the experimental data at RHIC and the LHC. On the contrary, the same experiment data cannot be explained within the picture of independent energy loss of the two prongs within the groomed jet.
