Abstract

Forward-backward (FB) multiplicity and momentum correlations of produced\nparticles between symmetrically located pseudorapidity (\η) intervals have\nbeen studied using the pQCD inspired EPOS3 model with and without\nhydrodynamical evolution of particles in proton-proton (pp) collisions at the\ncenter-of-mass energy, \√(s)=13 TeV. The pseudorapidity-gap (\η_gap)\ndependence of FB correlation strength is compared with our previously published\nresults at \√(s)= 0.9, 2.76 and 7 TeV. The study reveals that the general\ntrends of FB correlation strength at \√(s)=13 TeV are similar to our\nprevious observations at lower center-of-mass energies. We also find that the\n\δ\η-weightage average of FB correlation strength as a function of\ndifferent center-of-mass energies (\√(s)= 0.9, 2.76, 7 and 13 TeV) tends\nto saturate at very high energy.\n
