Coherent J∕*q Photoproduction at Midrapidity in Pb - Pb Collisions at %s&sub(NN) = 5.02 TeV / S.Acharya, B.Batyunya, R.A.Diaz, S.Grigoryan, A.Kondratyev, A.Kuznetsov, L.Malinina, K.Mikhaylov, P.Nomokonov, V.Pozdniakov, E.Rogochaya, A.Vodopyanov, [ALICE Collab.]. – Text : electronic // Physics Letters B. – 2025. – Vol. 871. – P. 139952. – URL: https://doi.org/10.1016/j.physletb.2025.139952. – Bibliogr.: 52.
The coherent J∕*q photoproduction cross section is measured for the first time at midrapidity in peripheral to semicentral Pb − Pb collisions at *% 𝑠&sub(NN) = 5.02 TeV. The centrality differential cross section d&sub(*d)∕d&sub(*g) is reported for the centrality range 40–90%, together with the doubly-differential cross section d &sup(2)*g∕dd𝑝&sub(T) , extracted in two peripheral centrality classes. The J∕*q mesons are reconstructed in the dielectron channel, in the rapidity interval |𝑦| < 0.9 using the ALICE central barrel detectors. The J∕*q cross section at midrapidity is statistically compatible to the earlier ALICE measurement at forward rapidity and at the same centre-of-mass energy, and shows only a mild centrality dependence over the covered range. Several sets of theoretical calculations taking into account the hadronic overlap in the collisions but ignoring possible final-state effects from a hot expanding medium are found to give a fairly good description of the current measurements within uncertainties.
