Abstract

Limits for the neutrino decay ν_H→ν_L+γ, where ν_H and ν_L are assumed to be massive neutrinos withm_VH>m_VL, are presented using data from the Solar Maximum Mission satellite taken in coincidence with the detected neutrino burst from SN 1987A. These limits are essentially independent of supernova models and are τ/m_ve>8.3×10¹⁴ s/eV and τ/m_{ν_μ,τ}>3.3×10¹⁴ s/eV for a thermal spectrum at a temperature T_ve = 3 MeV.
