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).SISSA20262026-05-22 10:28:22Neznano29507UDK: 539.1ISSN pri članku: 1029-8479DOI: 10.1007/JHEP04(2026)204COBISS_ID: 278840067Italija sl© The Authors.
