Description
The correlation between particles produced at various pesudorapidity values is an important probe to disentangle the underlying dynamics of multi-particle production in high energy collisions.
The long-range correlations are believed to be free from final-state effects.
The correlation strength ($b_{corr}$) has been studied for forward ($N_{F}$) and backward ($N_{B}$) charged partice multiplicities.
The $b_{corr}$ has been investigated as a function of gap between the forward and backward pesudorapidity windows as well as the width of these windows.
These $b_{corr}$ has also been studied for positively and negatively charged particle multiplicity in forward and backward intervals, respectively.
The strongly intensive fluctuation measure ($\Sigma$), which reduces to unity in absence of any inter-particle correlations, has also been investigated by employing the two extensive variables i.e., $N_{F}$ and $N_{B}$.
The effect of processes like multiparton interaction (MPI) and color reconnection (CR) is also taken into account.
The events have been simulated for proton-proton and Pb-Pb collisions at the Large Hadron Collider energies using the Pythia8 event generator.
