We conclude that the mass range 10 − 6 eV <~ m 3 / 2 <~ 2.3 × 10 − 5 eV is excluded by SN 1987A data. In terms of the scale of supersymmetry breaking Λ , the range 70 GeV <~ Λ <~ 300 GeV is not allowed.3 p.application/pdfeng(c) The American Physical Society, 1998Partícules (Física nuclear)Relativitat general (Física)EstelsSupersimetriaCol·lapse gravitacionalParticles (Nuclear physics)General relativity (Physics)StarsSupersymmetryGravitational collapseinfo:eu-repo/semantics/article508056info:eu-repo/semantics/openAccess
