Abstract: (Springer)

The standard model is extended with the

S_3

symmetry in which non zero

\theta _{13}

is obtained in the type I

+

II seesaw framework of neutrino mixing consistent with the current observation. Non zero contribution of CP asymmetry is discussed from the decay of scalar triplet in

S_3

extended standard model. Presence of right-handed neutrinos could explain both neutrino oscillation and non zero lepton asymmetry from the vertex correction of triplet decay, without including any other heavy triplet.
