Abstract
An inclusive baryon to meson enhancement with increase in multiplicity has been observed at intermediate pT in pp collisions at s = 7 TeV. Such a striking feature can be explained by approaches based on hydrodynamics and multi-parton interactions (MPI) coupled with color reconnection (CR) mechanism. In this paper, we investigate the multiplicity evolution of the charged particle yields associated with pions and protons selected from the intermediate pT region where the inclusive baryon to meson enhancement has been observed. The study has been performed using EPOS 3 (hydrodynamics) and PYTHIA 8 (MPI with CR) event generators for pp collisions at 7 TeV. We find that the response of the individual pion and proton triggered correlation towards these two mechanisms is different and can be used to disentangle the effect of one from the other. The current study can, therefore, provide important insights on the particle production mechanisms at intermediate pT in high multiplicity pp collisions at the LHC energies.
