      abstract     = {During a tidal disruption event, a star is torn apart by
                      the tidal forces of a supermassive black hole, with about
                      $50\%$ of the star’s mass eventually accreted by the black
                      hole. The resulting flare can, in extreme cases of
                      super-Eddington mass accretion, result in a relativistic
                      jet1,2,3,4. While tidal disruption events have been
                      theoretically proposed as sources of high-energy cosmic
                      rays5,6 and neutrinos7,8,9,10,11,12,13,14, stacking searches
                      indicate that their contribution to the diffuse
                      extragalactic neutrino flux is very low15. However, a recent
                      association of a track-like astrophysical neutrino
                      (IceCube-191001A16) with a tidal disruption event
                      (AT2019dsg17) indicates that some tidal disruption events
                      can accelerate cosmic rays to petaelectronvolt energies.
                      Here we introduce a phenomenological concordance scenario
                      with a relativistic jet to explain this association: an
                      expanding cocoon progressively obscures the X-rays emitted
                      by the accretion disk, while at the same time providing a
                      sufficiently intense external target of backscattered X-rays
                      for the production of neutrinos via proton–photon
                      interactions. We also reproduce the delay (relative to the
                      peak) of the neutrino emission by scaling the production
                      radius with the black-body radius. Our energetics and
                      assumptions for the jet and the cocoon are compatible with
                      expectations from numerical simulations of tidal disruption
                      events.},
