Neutrino masses in R-parity violating supersymmetric models

  title={Neutrino masses in R-parity violating supersymmetric models},
  author={Yuval Grossman Y. Grossman and Subhendu Rakshit},
We study neutrino masses and mixing in R-parity violating supersymmetric models with generic soft supersymmetry breaking terms. Neutrinos acquire masses from various sources: Tree level neutrino–neutralino mixing and loop effects proportional to bilinear and/or trilinear R-parity violating parameters. Each of these contributions is controlled by different parameters and have different suppression or enhancement factors which we identified. Within an Abelian horizontal symmetry framework these… CONTINUE READING
