Three-Pion Bose-Einstein Correlations Measured in Proton-Proton Collisions / R.Aaij, K.Ivshin, A.Solovev, [LHCb Collab.]. – Text : electronic // Journal of High Energy Physics. – 2025. – Vol. 2025, No. 8. – P. 174. – URL: https://doi.org/10.1007/JHEP08(2025)174. – Bibliogr.: 45.

A study on the Bose-Einstein correlations for triplets of same-sign pions is presented. The analysis is performed using proton-proton collisions at a centre-of-mass energy of *%s = 7 TeV, recorded by the LHCb experiment, corresponding to an integrated luminosity of 1.0 fb&sup(−1). For the first time, the results are interpreted in the core-halo model. The parameters of the model are determined in regions of charged-particle multiplicity. This measurement provides insight into the nature of hadronisation in terms of coherence, being consistent with the presence of coherent emission of pions.
