Description
High-multiplicity triggered events produced in pp collisions at $\sqrt{s}=13$ TeV collected by ALICE detector are analyzed to study the mean transverse momentum ($p_{\rm T}$) fluctuations. The study is inspired by the idea that non-monotonic changes in $p_{\rm T}$ correlations vary with energy and, if observed, may be taken as an indicator for the {\footnotesize QGP} formation. The finding reveals that the values of the two-particle correlator, $\sqrt{C_m}/M(p_T)_m$ decreases with increasing charged particle density and exhibits a power-law behavior similar to those reported for pp and Pb--Pb collisions at lower energies. In order to look for effects of jets and minijets, dependence of correlator, $\sqrt{C_m}/M(p_T)_m$ on charged particle density is examined by applying different $p_{\rm T}$ selection and comparing the behavior of the correlator observed for low $p_{\rm T}$ to high $p_{\rm T}$ ranges. The findings based on the data are also compared with the predictions of various Monte Carlo models.
