  The symmetry breaking of left right symmetric model around few TeV range
permits the existence of massive right handed neutrinos or gauge bosons. In
this work the decay of lightest right handed neutrinos in a class of minimal
left right symmetric model is analysed for the generation of adequate lepton
asymmetry. An analytical expression for the lepton asymmetry is developed. In
an attempt to achieve the required baryogenesis, we have imposed certain
constrains on the parameter space corresponding to low energy neutrino
oscillation parameters (especially {\theta} 13 ) and the three phases ( CP,
majorana and higher energy phase).
