Measurements of two-particle angular correlation along with the event-by-event fluctuations of conserved quantities such as net-charge, net-baryon, and net-strangeness provide potential information about the phase transition from hadronic to quark-gluon plasma phase of matter created in ultra-relativistic heavy-ion collisions. In this talk, I will discuss the charge-dependent correlations obtained in different collision geometries in pPb and PbPb systems. A wide variety of measurements suggest the existence of strong collectivity in collisions of small systems such as proton-proton (pp) and proton-nucleus (pPb) with hydrodynamic models or gluon saturation in the initial state as two theory alternatives showing consistency with the observations. These results raise the question of whether such phenomena may be present in even smaller systems. This talk will summarize the latest CMS results on the study of long-range particle correlations extended to photon-proton interactions using pPb collision. Such interactions provide unique initial conditions with event multiplicity lower than in pp and pPb systems but comparable with electron-positron and ep systems.
