However, it has been shown that the standard one-zone model cannot produce sufficiently high neutrino flux due to constraints from the X-ray data, implying more complex properties of the radiation zones in the blazar than that described by the standard one-zone model. In this work we investigate multi-epoch high-energy muon neutrino events associated with the blazar $TXS~0506+056$ occured in 2014-2015, 2017-2018, 2021-2022 and 2022-2023, respectively. We applied the so-called ``stochastic dissipation model'' to account for the neutrino-blazar associations detected in the four epochs simultaenously. This model describes a scenario in which the emission of the blazar arise from the superimposition of two components: a persistent component related to the quasi-stable state of the blazar and a transient component responsible for the sudden enhancement of the blazar's flux, either in electromagnetic radiation or in neutrino emission. The latter component could form at a random distance along the jet by a strong energy dissipation event. Under such assumption, the multi-epoch broadband spectral energy distribution (SED) can be well explained and the expected number of high-energy neutrino events is statistically realistic. The expected number of neutrino events in half-year is around 8.2, 0.07, 0.73 and 0.41, corresponding to the epoch in 2014-2015, 2017-2018, 2021-2022 and 2022-2023, respectively. Hence, our model self-consistently explains the episodic neutrino emission from $TXS~0506+056$.", "revisions": [ { "version": "v1", "updated": "2024-01-12T00:20:37.000Z" } ], "analyses": { "keywords": [ "broadband spectral energy distribution", "multi-epoch neutrino events", "high-energy muon neutrino events", "unified model", "sufficiently high neutrino flux" ], "note": { "typesetting": "TeX", "pages": 19, "language": "en", "license": "arXiv", "status": "editable" } } }
