Description
Two-particle number and transverse momentum correlations are sensitive probes of particle production and transport in AA collisions. Their shape and strength are sensitive to the interplay of all production processes, and are further influenced by transport mechanisms, including longitudinal, radial, and anisotropic flow. However, the correlations are also sensitive to instrumental effects, including distortions associated with space-charge effects in the Time Projection Chamber (TPC), to technical issues related to pile up rejection, suppression of contamination, and corrections for particle losses. It is thus a fundamental quality control for the ALICE data-taking machinery to perform analyses already completed and compare the results obtained with the new GEM readout, the new data-collecting machinery, and the new software framework, with those obtained with the prior TPC readout technology and overall scenario.
In this contribution, two-particle number and transverse momentum correlations in different multiplicity classes of pp collisions at $\sqrt{s} = 13.6\;\text{TeV}$ recorded by ALICE during the Run 3 at the LHC are reported. The very large datasets obtained in Run 3 will provide for a significant reduction of statistical and systematic uncertainties and enable more differential analyses of these correlations based on more varied and selective kinematic criteria. Results will be compared with previous results from Run 1 and Run 2 which, apart from validating the new data-taking machinery, will shed light on the evolution of these correlators with collision energies.
