A multistage framework for studying the evolution of jets and high- probes in small collision systems

Understanding the modification of jets and high- probes in small systems requires the integration of soft and hard physics. We present recent developments in extending the JET…
Effects of multi-scale jet-medium interactions on jet substructures
