### Description

We study nonperturbative flavor correlations between pairs of leading and next- to-leading charged hadrons within jets and their modifications in the presence of a QCD medium. A charge correlation ratio observable $r_{c}$, generalized from the balance function 1 which distinguishes between same-sign and opposite-sign charged pairs, is introduced. This observable $r_c$ is studied as a function of different kinematic variables in different colliding particle species using different Monte Carlo event generators. We demonstrate the feasibility of such measurements at the Electron Ion Collider in the context of hadronization studies 2. This will provide new tests of hadronization models and hopefully lead to improved quantitative understanding of nonperturbative QCD dynamics. Also, with robust understanding of hadronization using $r_c$, we examine its medium modification which will shed light on the jet quenching mechanisms in hadronization and in-medium jet evolution.
