Probing the dynamical evolution of QGP using charge-dependent correlations and fluctuations at CMS / Chatterjee, Sayan (Indian Inst. Tech., Madras) /CMS Collaboration
We present the first studies of net-charge fluctuations and charge-balance functions using the broad rapidity coverage of the CMS experiment. These types of event-by-event fluctuations are a powerful tool to characterize the thermodynamic properties of the quark-gluon plasma (QGP). [...]

Two-particle angular correlations of identified particles in pp collisions at $\sqrt{s}$ = 13 TeV with ALICE / Ruggiano, Daniela (Warsaw U. of Tech.)
Two-particle angular correlation is one of the most powerful tools to study the mechanism of particle production in proton--proton (pp) collision systems by relating the difference between the azimuthal angle ($\Delta\varphi$) and the rapidity ($\Delta y$) of the particles from a pair. [...]
