title: "Figure3_left_LSkaons" of "Multiplicity dependence of two-particle angular correlations of identified particles in pp collisions at $\mathbf{\sqrt{s} = 13}$ TeV"

description: Δφ projection for particle pair K⁻K⁻ + K⁺K⁺ across all multiplicity classes using the probability ratio correlation function C_P(Δφ).
description: Two-particle angular correlations explore particle production mechanisms and underlying event-wide phenomena present in the systems created in hadronic collisions. In this work, correlations are examined as a function of rapidity and azimuthal-angle differences (Δy, Δφ) for pairs of like- and unlike-sign pions, kaons, and (anti-)protons produced in pp collisions at √s = 13 TeV, measured with the ALICE detector. The two-particle correlation functions are provided together with Δy and Δφ projections and compared to Monte Carlo (MC) model predictions. For the first time, the measurement is performed as a function of the event's charged-particle density. The shapes of the correlation functions are studied in detail for each particle pair, for both mesons and baryons. Previous ALICE studies at √s = 7 TeV revealed an anticorrelation at small relative angles for baryon–baryon and antibaryon–antibaryon pairs, whose origin remains an open question. In this work, an approach accounting for the inverse multiplicity scaling of the correlation function is introduced to study the multiplicity dependence of the correlation functions in more detail, highlighting differences in the underlying sources of correlations, such as quantum-statistics, final-state interactions, and resonance decays. The puzzling near-side anticorrelation in baryon–baryon measurements is observed across all multiplicity classes and remains a challenge for models of particle production in pp collisions. Furthermore, the multiplicity dependence of meson–meson correlations provides an independent means to explore the sensitivity of current MC models to soft-QCD effects and hadronization dynamics. The presented measurements enrich the experimental picture of two-particle correlations in pp collisions and serve as valuable input for ongoing theoretical developments.
