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.
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.
DUNE's long-baseline program combined with near-detector and PRISM strategies is argued to be well-suited for detecting correlated deviations from the minimal three-flavor neutrino framework.
