Description
The core-corona picture implemented in the EPOS~3 model has successfully described the multiplcity dependence of particle production in proton--proton (pp) and proton--nucleus collisions at LHC energies.
The inclusion of viscous hydrodynamics plays a key role in describing the observed features of data. It suggests an interpretation of new phenomena assuming the formation of a small drop of the Quark-Gluon Plasma.
However, initial state effects produce similar signals. Therefore, novel ideas are of crucial importance in order to make a comprehensive comparison between models and data.
In this regard, we propose a strategy in order to enhance or suppress the effects arising from the core component of the EPOS~3 model using measureable quantities. In doing so, based on our earlier studies, we investigate
the simulated sample differentially as a function of event charged-particle multiplicity and the transverse momentum ($p_{\rm T}$) of the leading jet ($p_{\rm T}^{\rm jet}$) reconstructed at mid-pseudorapidity ($|\eta|<1$).
The baryon-to-meson and hyperon-to-pion particle ratios as well as the average $p_{\rm T}$ are determined as a function of multiplicity and $p_{\rm T}^{\rm jet}$ in inelastic pp collisions at $\sqrt{s}=$ 7\,TeV.
The results suggest sizable effects that could be compared to experimental data.
