ABSTRACT

We present a neutrino model realized by linear seesaw mechanism incorporating A4flavour symmetry. The light neutrino mass matrix is obtained from the model which is compared with that obtained experimentally. This gives us a set of six real equations which is later solved to obtain free parameters of neutrino mixing, i.e., lightest neutrino mass, Dirac CP violating phase ? and two Majorana phases, ? and ?. A full parameter scan of the recent 3? global fit values of neutrino oscillation parameters is done to find the desired unknown parameters. Using this data of neutrino oscillation parameters we find the branching ratio of the cLFV decay ??e+? for our LSS model, which is found to lie within present limits of the same. Since linear seesaw model is a low scale model, this is testable in experiments, as well as prediction of cLFV decay obtained in this model can be tested when future measurements are done.
