Abstract

We consider neutrino masses generated at tree level and at one loop, through fermion--sfermion loop diagrams, in the MSSM with R-parity violation. Using the (3× 3) mass and mixing matrices for three generations of neutrinos and the present experimental results on neutrinos from laboratories and astrophysics simultaneously, we put bounds on both trilinear (λ_ijk, λ'_ijk) and bilinear (μ_e,μ_μ,μ_τ) R-parity-violating couplings.
