Rapidity and Multiplicity Dependence of Charged-Particle Flow in pPb Collisions at *%s&sub(NN)=8.16 TeV / R.Aaij, K.Ivshin, A.Solovev, [LHCb Collab.]. – Text : electronic // Journal of High Energy Physics. – 2025. – Vol. 2025, No. 10. – P. 124. – URL: https://doi.org/10.1007/JHEP10(2025)124. – Bibliogr.: 75.

The elliptic and triangular flow of charged particles are measured using two-particle angular correlations in pPb collisions in the pseudorapidity range 2.0 < |η| < 4.8. The data sample was collected by the LHCb experiment in 2016 at a centre-of-mass energy per nucleon pair of *%s&sub(NN)=8.16 TeV, containing in total approximately 1.5 billion collision events. Non-flow contributions are obtained in low-multiplicity collisions and subtracted to extract the flow harmonics. The results are presented as a function of event multiplicity and hadron transverse momentum. Comparisons with a full (3+1)D dynamic model indicate that it overestimates the measured elliptic flow. A comparison between the forward and backward regions reveals no significant differences in flow parameters, suggesting that final-state effects may dominate over initial-state effects in the origin of flow in small systems.
