Abstract Recent studies on high-multiplicity events in small collision systems (proton-proton and proton-lead) have drawn considerable research interest toward the possibility of formation partonic medium such systems. One important consequences dense is quenching high-momentum final-state particles, resulting several experimental observations as suppression nuclear modification factor , jet shape observable fragmentation ( ) distributions, etc . In this work, we study for inclusive charged-particle jets proton-proton (pp) collisions at = 13 TeV using PYTHIA 8 Monash 2013 Monte Carlo simulation. We show that color reconnection (CR) multiparton interaction (MPI) mechanisms can lead to an increased rate production. also find MPI CR change gluonic contribution result significant compared those minimum bias 10 20 GeV/ c notice a direct connection with amount : larger number MPIs and/or contribution,
