Details

We report the charge dependent two particle differential correlation function in PbPb, pPb and pp collisions
in \sqrt_{S_{NN}} = 5.02 TeV, \sqrt_{S_{NN}} = 8.16 TeV and \sqrt_{S_{NN}} = 13TeV.
The correlation function is used as a probe to study the charge creation mechanism in high energy heavy ion collisions. This is the first time measurement using the electric charge balance function in the relative pseudorapidity (∆η) and azimuthal angle (∆φ) using the CMS detector at the Large Hadron Collider. We observed the multiplicity dependence of the balance function both in relative pseudo-rapidity(∆η) and relative-azimuthal angle(∆φ). We have constructed the charge balance function using the like and unlike charge pairs to quantify the correlation of the emitted particles. The charge dependent study of the correlation function shows the width of the balance function increases from more central collisions to peripheral collisions. The narrowing of the width indicates the late hadronization and the widening of the width indicates the early hadronization.
