Measurements of the $\beta^-$ spectrum of tritium give the most precise direct limits on neutrino mass. Project 8 will investigate neutrino mass using Cyclotron Radiation Emission Spectroscopy (CRES) with an atomic tritium source. CRES is a new experimental technique that has the potential to surmount the systematic and statistical limitations of current-generation direct measurement methods. Atomic tritium avoids an irreducible systematic uncertainty associated with the final states populated by the decay of molecular tritium. Project 8 will proceed in a phased approach toward a goal of 40 meV/c$^2$ neutrino-mass sensitivity.

  1. Measuring neutrino mass and asymmetry through galaxy pairwise peculiar velocity

    astro-ph.CO 2026-04 unverdicted novelty 7.0

    Galaxy pairwise peculiar velocities from Cosmicflows-4 yield M_ν = 0.24^{+0.34}_{-0.18} eV and η² = 2.14^{+0.30}_{-0.32} (7σ non-zero asymmetry) in the CMB framework, consistent with prior Planck results.

    hep-ph 2026-05 unverdicted novelty 6.0

    A minimal dark SU(2)_D model with anomaly cancellation and Z4 symmetry generates a rank-two Dirac neutrino mass matrix enforcing one exactly massless neutrino.

  3. The $\beta$-decay spectrum of Tritiated graphene: combining nuclear quantum mechanics with Density Functional Theory

    hep-ph 2026-06 unverdicted novelty 5.0

    A Dirac scoto-seesaw framework with chiral U(1)B-L charges (-4,-4,5) generates atmospheric neutrino mass at tree level and solar mass radiatively, stabilizes dark matter with residual Z6, and suppresses Z' dilepton decays.

  5. A Type-I Seesaw Framework with Non-Holomorphic Modular Symmetry

    hep-ph 2026-04 unverdicted novelty 5.0

    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.
