Final measurements of charged particle production as a function of NT in pp, p--Pb and Pb--Pb collisions at √sNN = 5.02 TeV will be presented in the toward, away and transverse regions. The UE contributions measured in the transverse region are subtracted from the toward and the away regions to search for jet-like modifications in small systems. The jet-like signals are studied both as a function of NT and leading particle pT.
Final results of π, K, and p production as a function of RT in pp collisions at √s = 13 TeV are presented to explore the particle species dependence. In particular, the focus will be on very low (high) RT to isolate the ``jet'' (UE) contributions.
All the above results are compared with predictions from QCD-inspired Monte Carlo event generators such as PYTHIA and EPOS LHC.
