These regions are defined event-by-event relative to the azimuthal direction of the charged trigger particle, which is the reconstructed particle with the largest transverse momentum ( p(trig) (T)) in the range 8 < p(trig) (T) < 15 GeV/c. The toward and away regions contain the primary and recoil jets, respectively. Both regions are accompanied by the underlying event (UE). In contrast, the transverse region perpendicular to the direction of the trigger particle is dominated by the so-called UE dynamics, and includes also contributions from initial- and final-state radiation. The relative transverse activity classifier, R-T = N-ch(T)/< N-ch(T)>, is used to group events according to their UE activity, where < N-ch(T)> is the charged-particle multiplicity per event in the transverse region and.< N-ch(T)>. is the mean value over the whole analysed sample. The energy dependence of the R-T distributions in pp collisions at root s = 2.76, 5.02, 7, and 13TeV is reported, exploring the Koba-Nielsen-Olesen (KNO) scaling properties of the multiplicity distributions. The first measurements of charged-particle pT spectra as a function of RT in the three azimuthal regions in pp, p-Pb, and Pb-Pb collisions at root sNN = 5.02TeV are also reported. Data are compared with predictions obtained from the event generators PYTHIA 8 and EPOS LHC. This set of measurements is expected to contribute to the understanding of the origin of collective-like effects in small collision systems (pp and p-Pb).
