LSND, solar and atmospheric neutrino oscillation experiments and   R-parity violating Supersymmetry
  With only three flavors it is possible to account for various neutrino oscillation experiments. The masses and mixing angles for three neutrinos can be determined from the available experimental data on neutrino oscillation and from the astrophysical arguments. We have shown here that such masses and mixing angles which can explain atmospheric neutrino anomaly, LSND result and the solar neutrino experimental data, can be reconciled with the R-parity violating Supersymmetric Models through lepton number violating interactions. We have estimated the order of magnitude for some lepton number violating couplings. Our analysis indicates that the lepton number violation is likely to be observed in near future experiments. From the data on neutrino oscillation and the electric dipole moment of electron, under some circumstances it is possible to obtain constraint on the complex phase of some supersymmetry breaking parameters in R-parity violating Supersymmetric models.
