TeV scale leptogenesis, θ13 and doubly charged particles at LHC

We explore a realistic supersymmetric SU(2)L×SU(2)R×U(1)B−L model spontaneously broken at around 1012GeV. The presence of D- and F-flat directions gives rise to TeV mass doubly charged particles which can be found at the LHC. We implement TeV scale leptogenesis and employing both type I and II seesaw, the three light neutrinos are partially degenerate with masses in the 0.02-0.1 eV range. The effective mass parameter for neutrinoless double beta decay is 0.03-0.05 eV. We also find the interesting relation tan2θ13≃sin2θ12tan2θ23(Δm⊙2Δmatm2)≲0.02.
