Abstract

Bilinear R-parity violating supersymmetric model is a viable model which can explain the smallness of neutrino masses and the mixing pattern in the lepton sector. In this model, there is a common set of parameters which determine the neutralino and chargino masses, also determine the neutrino masses and the anomalous magnetic moment of muon, $(g-2)_\mu$. From the experimental data on neutrino masses and mixing angles, and also from the fact that the experimentally measured value of $(g-2)_\mu$ differs from the corresponding standard model value by 3$\sigma$, we have analyzed some constraints on these model parameters. Constraints on these model parameters are obtained for some values of supersymmetry breaking soft parameters. These constraints can set upper and lower bounds on the chargino masses of this model.
