One-loop threshold corrections in the minimal U(1)_{L_mu-L_tau} seesaw model break the tree-level two-zero minor structure, relaxing the lower bound on total neutrino mass and easing cosmological tension.
Gravitational production of neutrinos with time-dependent mixing during inflation is enhanced but remains bounded by an abundance Y ≲ 10^{-11}.
Flavon fields from a TM1 flavor symmetry neutrino model can act as scalar singlets to achieve successful TeV-scale leptogenesis and reproduce observed neutrino data without mass degeneracy among right-handed neutrinos.
Dirac right-handed neutrinos in a U(1)_{B-L} Z' portal model produce observable ΔN_eff that, together with direct/indirect detection and collider bounds, carves out testable WIMP and FIMP dark-matter regions.
Non-holomorphic modular symmetry in a Type-I seesaw model fits normal hierarchy neutrino data with chi2 min 7.06 but rules out inverted hierarchy.
The paper identifies promising parameter regions for observing same-sign tetralepton events from charged Higgs pair and single production decaying to muons and heavy neutral leptons at μTRISTAN.
Z4-symmetric Type I seesaw fits neutrino data with minimal parameters and enables freeze-in dark matter plus resonant leptogenesis via soft symmetry breaking.
In an E6-derived ψ'SM extension, a singlet fermion acts as freeze-in dark matter with relic density set by scalar decays for masses from a few MeV to hundreds of GeV, while type-I seesaw neutrinos simultaneously produce the observed baryon asymmetry via leptogenesis.
Conceptual discussion framing flavor as an incomplete SM structure and arguing DUNE's phased program can search for correlated departures from three-flavor neutrino mixing.
