Model Study of Two Particle Correlations with Identified Trigger Particles in p-Pb Collisions at LHC Energy

Abstract

We report results of baryon-hadron and meson-hadron correlations at intermediate $p_{T}$, where an anomalous enhancement in the inclusive baryon-to-meson ratio has been observed in p-Pb collisions at $\sqrt{s_{NN}} = 5.02$ TeV. The choice of the trigger $p_{T}$ region (1.5/2.0 $<p{_T}< 4.0$ GeV/${c}$) is of particular interest as it is believed to have contributions from both hard (fragmentation) and soft (hydrodynamics and/or coalescence model of hadronization) processes of particle production mechanism. Using the two particle correlation technique, the multiplicity evolution of the pion- and proton-triggered jet-like yields has been studied to explore the underlying mechanisms of particle production in the intermediate $p_{T}$ (trigger $p_{T}$) region.
