title: "Table 27" of "Charged-particle production as a function of the relative transverse activity classifier in pp, p$-$Pb, and Pb$-$Pb collisions at the LHC"

description: $p_\mathrm{T}$-integrated yield normalised to $$ as a function of $R_\mathrm{T}$ in the toward region using events with trigger particles $80.5~\mathrm{GeV}/c$ for Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02~\mathrm{TeV}$
description: Measurements of charged-particle production in pp, p-Pb, and Pb-Pb collisions in the toward, away, and transverse regions with the ALICE detector are discussed. 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 ($p_\mathrm{T}^\mathrm{trig}$) in the range $8 &lt; p_\mathrm{T}^\mathrm{trig} &lt; 15~\mathrm{GeV}/c$. 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, $R_\mathrm{T}=N_\mathrm{ch}^\mathrm{T}/\langle N_\mathrm{ch}^\mathrm{T}\rangle$, is used to group events according to their UE activity, where $N_\mathrm{ch}^\mathrm{T}$ is the charged-particle multiplicity per event in the transverse region and $\langle N_\mathrm{ch}^\mathrm{T}\rangle$ is the mean value over the whole analysed sample. The energy dependence of the $R_\mathrm{T}$ distributions in pp collisions at $\sqrt{s}=2.76, 5.02, 7$, and $13~\mathrm{TeV}$ is reported, exploring the Koba-Nielsen-Olesen (KNO) scaling properties of the multiplicity distributions. The first measurements of charged-particle $p_\mathrm{T}$ spectra as a function of $R_\mathrm{T}$ in the three azimuthal regions in pp, p-Pb, and Pb-Pb collisions at $\sqrt{s_\mathrm{NN}}=5.02~\mathrm{TeV}$ are also reported. Data are compared with predictions obtained from the event generators $\mathrm{PYTHIA}~8$ and $\mathrm{EPOS}~\mathrm{LHC}$. 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).

title: "Table 2" of "Pseudorapidity dependence of anisotropic flow and its decorrelations using long-range multiparticle correlations in Pb-Pb and Xe-Xe collisions"

description: $v_{3}\{2\}$ versus $\eta$ for $x^{\pm}$ in $\mathrm{Pb}-\mathrm{Pb}$ at $\sqrt{s_{\mathrm{NN}}}=5.023\,\mathrm{Te\!V}$
description: The pseudorapidity dependence of elliptic ($v_{2}$), triangular ($v_{3}$), and quadrangular ($v_{4}$) flow coefficients of charged particles measured in Pb-Pb collisions at a centre-of-mass energy per nucleon pair of $\sqrt{s_{\mathrm{NN}}}=5.02\,\mathrm{TeV}$ and in Xe-Xe collisions at $\sqrt{s_{\mathrm{NN}}}=5.44\,\mathrm{TeV}$ with ALICE at the LHC are presented. The measurements are performed in the pseudorapidity range $-3.5 &lt; \eta &lt; 5$ for various centrality intervals using two- and multi-particle cumulants with the subevent method. The flow probability density function (p.d.f.) is studied with the ratio of flow coefficient $v_2$ calculated with four- and two-particle cumulant, and suggests that the variance of flow p.d.f. is independent of pseudorapidity. The decorrelation of the flow vector in the longitudinal direction is probed using two-particle correlations. The results measured with respect to different reference regions in pseudorapidity exhibit differences, argued to be a result of saturating decorrelation effect above a certain pseudorapidity separation, in contrast to previous publications which assign this observation to non-flow effects. The results are compared to $3+1$ dimensional hydrodynamic and the AMPT transport model calculations. Neither of the models is able to simultaneously describe the pseudorapidity dependence of measurements of anisotropic flow and its fluctuations. The results presented in this work highlight shortcomings in our current understanding of initial conditions and subsequent system expansion in the longitudinal direction. Therefore, they provide input for its improvement.
