20.500.12556/DiRROS-29507 Neutrino masses, ▫&δ_{PMNS}, and m[sub]{ββ} in SO(10)$▫ We explore the leptonic sector of a recently proposed supersymmetric SO(10) model with supersymmetry breaking in the 3–10 TeV range. A new ingredient in this work is the requirement that the observed baryon asymmetry is explained via non-thermal leptogenesis, which can be realized in a large class of supersymmetric hybrid inflation models including SO(10). We provide estimates for the masses of the three Standard Model neutrinos (with the lightest mass m1 ≈ 5 meV) as well as the three right-handed neutrinos (M1 ≈ 109 GeV and M2,3 ≈ 1013 GeV). The best fit estimate for the leptonic CP violating parameter δPMNS ≈ 235°, and the value of the neutrinoless double beta decay mass parameter mββ ≈ 0.18 meV. A numerical analysis broadens the predicted range for δPMNS (100°–300°), but leaves largely intact the predictions for the six (light and heavy) neutrino masses and mββ. Our statistical analysis, which yields the likelihood-predicted ranges of the observables, is fully consistent with JUNO’s newly released first measurement of reactor neutrino oscillations in the -sin2 θ12 plane, with JUNO improving the precision by a factor of 1.6 relative to the combination of all previous measurements. The implementation of successful non-thermal leptogenesis allows us to provide estimates for the inflaton mass (mχ ≈ 7 × 109 GeV) and the reheating temperature (TRH ≈ 4 × 106 GeV). grand unification supersymmetry supersymmetric SO(10) model neutrino masses and CP violations non-thermal leptogenesis veliko poenotenje supersimetrija supersimetrični model SO(10) mase nevtrinov in CP-kršitev netermična leptogeneza true false true SISSA Italija Angleški jezik Slovenski jezik © The Authors.
