  Di-jet observables are excellent probes to study the effect of jets in dense
systems. Interacting Lund strings will affect jet observables and suggests a
new common mechanism responsible for jet modification in p-A and A-A. In this
proceeding, we present our new implementation of the string shoving mechanism
in PYTHIA8 which lets us study the effects on jet observables in p-p and
nuclear collisions. We also present preliminary results showing the effects in
hadron-jet correlation studies.
