Description
Event-by-event fluctuations of mean transverse momentum, $\langle p_{\rm{T}}\rangle$, help to characterize the properties of the system created in heavy-ion collisions and are linked to the phase transition dynamics from quark-gluon plasma (QGP) to a hadron gas. In this contribution, $\langle p_{\rm{T}}\rangle$ fluctuations of charged particles produced in pp at $\sqrt{s}= 5.02$ TeV, Xe-Xe and Pb-Pb collisions at $\sqrt{s_{\rm{NN}}}=$ 5.44 and 5.02 TeV, respectively, are studied as a function of charged-particle multiplicity. In Xe-Xe and Pb-Pb collisions, the multiplicity dependence deviates significantly from a simple power law scaling, which is qualitatively expected from radial flow in mid to central heavy-ion collisions. In pp collisions, the correlation strength is studied as a function of transverse spherocity to examine the effects of jets. The strength and multiplicity dependence of jetty and isotropic events are compared with QCD-inspired MC models.
