We make a general analysis of neutrino phenomenology for the case neutrino masses are generated by the see-saw mechanism with just two right handed neutrinos. We find general constraints on leptogenesis and lepton flavour violating processes. We also analyse the predictions following from a nontrivial texture zero structure.

    hep-ph 2025-08 unverdicted novelty 6.0 of 10

    Minimal setup with one RHN and Higgs inflaton generates neutrino masses, baryon asymmetry via Affleck-Dine leptogenesis, and matches PLANCK/ACT inflation data with a small parameter space.

  3. Minimal Multi-Majoron Model

    hep-ph 2025-07 conditional novelty 6.0 of 10

    The minimal multi-Majoron model is a UV-complete seesaw framework in which two Majoron VEVs set hierarchical right-handed neutrino masses and generate a combined cosmic-string and first-order-transition gravitational ...

    hep-ph 2024-12 conditional novelty 6.0 of 10

    A seesaw model with spontaneously broken lepton number can simultaneously explain dark matter as a freeze-in Majoron and the baryon asymmetry through resonant leptogenesis, with one set of dimension-five operators con...

  5. Minimal Majoron Dark Matter from a Discrete $Z_N$ Gauge Symmetry

    hep-ph 2026-07 conditional novelty 5.0 of 10

    Discrete Z_N-protected majoron dark matter excludes Z_5, leaves Z_7/Z_11/Z_13 viable, and predicts a 1–10 MeV Z_7 majoron testable by COSI through 511 keV and γγ lines.

    hep-ph 2026-06 unverdicted novelty 5.0 of 10

    Projections indicate the FPF at FCC-hh can extend reach for light long-lived heavy neutrinos and Z' bosons in chiral U(1) models beyond existing experiments via meson decays and bremsstrahlung.

  7. Gravitational waves from seesaw assisted collapsing domain walls

    hep-ph 2025-12 conditional novelty 5.0 of 10

    Right-handed-neutrino couplings generate the energy bias that collapses Z2 domain walls, linking the type-I seesaw mass scale to observable gravitational-wave peaks and to resonant leptogenesis.

  8. Analytic formulation of Leptogenesis with neutrino oscillation data employing the general parametrization for neutrino mass matrix

    hep-ph 2025-06 conditional novelty 5.0 of 10

    Analytic CP asymmetry formulas from the Casas-Ibarra parametrization give minimum right-handed neutrino masses for successful leptogenesis, down to about 132 GeV with a neutrinophilic Higgs doublet and non-thermal production.

  9. Gravitational wave signatures of dark sector portal leptogenesis

    hep-ph 2025-04 conditional novelty 5.0 of 10

    A Z2-odd dark sector with a heavy fermion and two scalars enables TeV-scale leptogenesis and produces LISA-visible gravitational waves from a strong electroweak phase transition.

  11. Right-handed neutrinos: seesaw models and signatures

    hep-ph 2025-02 conditional novelty 1.0 of 10

    A pedagogical review that explains how adding right-handed neutrinos can generate small neutrino masses through seesaw mechanisms and what experimental signatures such models predict.
