Description

The ALICE experiment at the LHC is designed to investigate the properties of the Quark-Gluon Plasma by studying high-energy A--A collisions. Medium effects like parton energy loss can be examined by measuring the production of charged particles at high transverse momentum ($\textit{p}_{\text{T}}$). In particular, the correlation between $\textit{p}_{\text{T}}$ spectra and event multiplicity of charged particles can give a handle on the different production mechanisms of charged particles.
In this poster, we report on charged-particle $\textit{p}_{\text{T}}$ spectra as a function of the event multiplicity in pp collisions at $\sqrt{s} =$ 2.76, 5.02, 7 and 13 TeV as well as in p-Pb and Pb--Pb collisions at $\sqrt{s_{\text{NN}}} =$ 5.02 TeV to study the energy and system size dependence. By comparing to QCD-inspired models, this measurement can help in understanding the event multiplicity dependence of charged-particle production mechanism.
