"Soft Hadronic Probes: Particle Correlations and Collectivity in heavy-ion Collisions"
Prof. Prabhat Ranjan Pujahari
The Indian Institute of Technology Madras

Abstract: Particle correlations and collectivity (the latter refers to more than 2-particle correlations) are important directions in analyzing heavy-ion collisions to probe the system formed in such collisions. In this talk, I will focus on some of the recent measurements on this topic by our group at IIT Madras using the CMS experimental data. I start with a comparative analysis among pPb, PbPb, and XeXe collisions, which provides insights into medium interactions in different collision environments. In more detail, I discuss the differential Fourier coefficients (vn) in transverse momentum and multiplicity to explore potential medium effects on high-pT particles. In addition, I show how Investigations of XeXe collisions allow us to probe nuclear deformation effects and compare the dependence of flow harmonics on system size and geometry with PbPb collisions. Measurements of multiparticle mixed harmonic cumulants provide constraints on initial-state parameters and QGP evolution. Lastly, I discuss how the two-particle correlation measurements can be used to probe the effect of longitudinally boosted flowing medium on the near-side jet-peak structure.
