Investigating high energy proton proton collisions with a multi-phase transport model approach based on PYTHIA8 initial conditions

The striking resemblance of high multiplicity proton-proton (pp) collisions at the LHC to heavy ion challenges our conventional wisdom on formation Quark-Gluon Plasma (QGP). A consistent explanation collectivity phenomena in pp will help us understand mechanism that leads QGP-like signals small systems. In this study, we introduce a transport model approach connecting initial conditions provided by PYTHIA8 with subsequent AMPT rescatterings study collective behavior energy collisions. dependence light hadron productions from is reasonable agreement $\sqrt{s}=13$ TeV experimental data.
