Jet substructure modifications in a QGP from multi-scale description of jet evolution with JETSCAPE
2019 January 11
The modification of jet substructure in relativistic heavy-ion collisions is studied using JETSCAPE, a publicly available software package containing a framework of Monte Carlo event generators. Multi-stage jet evolution in JETSCAPE provides an integrated description of jet quenching by combining multiple models with each becoming active at different stages of the parton shower evolution. A variety of jet substructure modifications for different aspects of jet quenching are shown by demonstrating jet shapes and jet fragmentation functions from some combinations and settings of jet energy loss models with medium background provided by $(2+1)$-D VISHNU with TRENTO+freestreaming initial conditions. Results reported here are from simulations performed strictly within JETSCAPE framework.
