Title: Supernova constraints on massive (pseudo)scalar coupling to neutrinos

Abstract

In this paper we derive constraints on the emission of a massive (pseudo)scalar S from annihilation of neutrinos in the core of supernovae through the dimension-4 coupling νν S , as well as the effective dimension-5 operator 1/Λ(νν)( SS ). While most of earlier studies have focused on massless or ultralight scalars, our analysis involves scalar with masses of order eV–GeV which can be copiously produced during (the explosion of supernovae, whose core temperature is) generally of order T ∼ O O (10) MeV. From the luminosity and deleptonization arguments regarding the observation of SN1987A, we exclude a large range of couplings 10{sup −12} ∼< | g {sub αβ}|∼< 10{sup −5} for the dimension-4 case, depending on the neutrino flavours involved and the scalar mass. In the case of dimension-5 operator, for a scalar mass from MeV to 100 MeV the coupling h {sub αβ} get constrained from 10{sup −6} to 10{sup −2}, with the cutoff scale explicitly set Λ = 1 TeV. We finally show that if the neutrino burst of a nearby supernova explosion is detected by Super-Kamiokande and IceCube, the constraints will be largely reinforced.
