摘要：

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 x 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 (lambda (ijk), lambda (ijk)') and bilinear (mu (e), mu (mu), mu (tau)) R-parity-violating couplings.
