Evidence of different fractal behavior in EPOS3 simulated p-p events at √s = 0.9 TeV and 7 TeV: a study using visibility graph technique

Abstract

We have performed a study to search for the evidence of fractality in multiparticle production process at LHC energy regime using a non conventional tool visibility graph technique. P-p events at centre of mass energy 0.9 TeV and 7 TeV are generated using EPOS3 MC without hydro dynamical evolution option. Fractal properties have been studied by mapping the event-by-event pseudo rapidity distributions of produced charged particles into scale-free network in detail. The analysis reveals the presence of fractal nature in fluctuation pattern of charged particles produced in p-p events at two different energies and also manifests that the fractal behavior depends on centre of mass energy.
