The forward-backward long-range multiplicity correlations in proton-proton collisions at LHC energies



Primary authors

Abstract content

The forward-backward multiplicity correlations are important for the overall event characterization and to extract information on non-pertubative hadronic processes. In this work we present a study of this correlations based on p+p collisions generated with PYTHIA event generator at LHC energies with different initial conditions of the events to show how it is related with the hadronization mechanism, as well as to multiple partonic interactions and consequently the degree of hardness of the collisions. The effect of the QCD color reconnection strength is presented for minimum bias and jetty-like events, demonstrating the possibility to use these correlations to investigate underlying events. Finally, the comparison with available data suggests that forward-backward multiplicity correlations could be useful tools to disentangle phenomena in QCD processes.
