Description

This analysis investigates forward-backward (FB) multiplicity correlations in proton-proton (pp) collisions at $\sqrt{s} = 13$ TeV, using two prominent event generators: PYTHIA8, based on the Lund String model, and HERWIG7, which utilizes the Cluster Hadronization model. Simulated events were analyzed within varying pseudorapidity ($\eta$) windows, applying a transverse momentum ($p_{\rm{T}}$) range of 0.2$–$2.0 GeV/$c$. The study focuses on FB multiplicity correlations across different transverse spherocity regions, classifying events as jetty, intermediate, or isotropic. The results reveal that FB correlations systematically decrease with increasing pseudorapidity separation ($\eta_{sep}$), with Herwig consistently producing stronger correlations than Pythia. Among the spherocity regions, isotropic events exhibit the highest correlations, while jetty events display the weakest. These insights enhance our understanding of the relationship between event topology and particle production mechanisms in high-energy collisions.
