Abstract
The first measurement of the polarisation of coherently photoproduced J / ψ mesons in ultra-peripheral Pb–Pb collisions, using data at s NN = 5.02 TeV, is presented. The J / ψ meson is measured via its dimuon decay channel in the forward rapidity interval − 4.0 < y < − 2.5 using the ALICE detector at the CERN LHC. An event sample corresponding to an integrated luminosity of 750 μ b − 1 ± 5% (syst) is analysed. Hadronic activity is highly suppressed since the interaction is mediated by a photon. The polar and azimuthal angle distributions of the decay muons are measured, and the polarisation parameters λ θ , λ φ , λ θφ are extracted. The analysis is carried out in the helicity frame. The results are found to be consistent with a transversely polarised J / ψ . These values are compared with previous measurements by the H1 and ZEUS experiments. The polarisation parameters of coherent J / ψ photoproduction in Pb–Pb collisions are found to be consistent with the s -channel helicity conservation hypothesis.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
