Erratum to: Interactions of astrophysical neutrinos with dark matter: a model building perspective (Journal of High Energy Physics, (2019), 2019, 1, (95), 10.1007/JHEP01(2019)095)

Abstract

In ref. [1] we studied whether the neutrino-dark matter (DM) interactions can cause a suppression of astrophysical neutrino flux. We singled out the interactions which reduce the neutrino flux by (Formula presented.) 1%, dubbed as ‘significant flux suppression’ throughout the paper. In light of the collider and electroweak precision constraints, we concluded that out of the eleven effective and three renormalisable neutrino-DM interactions studied in ref. [1], three could still lead to at least 1% suppression of astrophysical neutrino flux at IceCube. These three scenarios involve ultralight scalar DM interacting with neutrinos through (i) Topology I 3 from eq. (3.3), (ii) Topology III in section 3.3, and (iii) vector-mediated interaction in section 4.3.3 of ref. [1]. In this erratum we add that, as the Big Bang Nucleosynthesis (BBN) constraints forbid neutrinos to be in thermal equilibrium with light scalar DM after the neutrino decoupling epoch, two out of the aforementioned three scenarios fail to lead to any significant flux suppression. To be precise, Topology III in section 3.3 and vector-mediated interaction in section 4.3.3 cannot lead to significant neutrino flux suppression, while Topology I 3 still can. The BBN bounds on these three scenarios are discussed in a more detail in the next section. © 2021, The Authors.
