TL;DR: In this paper, the cosmological constraints on supersymmetric theories with a new stable particle were considered and bounds on the parameters in the lagrangian which govern its mass and couplings were derived.

TL;DR: In this paper, the phenomenology of lepton-number violation is analyzed in low-energy models in which R parity is explicitly broken by superrenormalizable operators, and the photino is able to decay, avoiding a stringent cosmological lower bound.

TL;DR: In this paper, the cosmological constraints on unstable particles with masses O(m W ) were considered, and it was shown that these constraints are not as restrictive as those from the dissociation of light elements.

TL;DR: If the Universe contains a nearly critical density of photinos which are also assumed to constitute the dark matter in the authors' galactic halo, then gravitational trapping by the Sun and ensuing annihilation in the solar core yields a significant flux of approx.250-MeV neutrinos which results in about 2 neutrino-induced events per kiloton-year in an underground proton-decay detector.
Abstract: If the Universe contains a nearly critical density of photinos which are also assumed to constitute the dark matter in our galactic halo, then gravitational trapping by the Sun and ensuing annihilation in the solar core yields a significant flux of \ensuremath{\sim}250-MeV neutrinos. This results in about 2 neutrino-induced events per kiloton-year in an underground proton-decay detector.

TL;DR: In this article, a supersymmetric extension of the standard SU (2) L ×U(1) model is proposed, which provides a natural framework for spontaneous breakdown of global lepton number symmetry leading to a doublet majoron with neutrino as its supersymetric partner, and the existence of a light mass (∼100 keV) scalar boson very weakly coupled to matter.
