Abstract

A study of B⁺ → J/ψηK⁺ decays, followed by J/ψ → μ⁺μ⁻ and η → γγ, is performed using a dataset collected with the LHCb detector in proton-proton collisions at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 9 fb⁻¹. The J/ψη mass spectrum is investigated for contributions from charmonia and charmonium-like states. Evidence is found for the B⁺ → (ψ₂(3823) → J/ψη)K⁺ and B⁺ → (ψ(4040) → J/ψη)K⁺ decays with significance of 3.4 and 4.7 standard deviations, respectively. This constitutes the first evidence for the ψ₂(3823) → J/ψη decay.
