abstract

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 Cosmic Neutrino Masses Independently of Dark Energy

    astro-ph.CO 2026-07 accept novelty 6.0 of 10

    Two dark-energy-robust cosmological routes bound ∑mν to <0.152 eV (marginalized) and <0.41 eV (late-Universe-free), with the latter independent of tested w(a) models by construction.

  2. Neutrino mass and leptogenesis in the non-SUSY modular $A^\prime_5$ inverse seesaw model

    hep-ph 2026-03 conditional novelty 6.0 of 10

    Three non-SUSY A5-prime modular inverse-seesaw models fit neutrino oscillation data and can generate the observed baryon asymmetry via TeV-scale resonant leptogenesis.

  3. The real-time data processing and acquisition system for Project 8 Phase II

    physics.ins-det 2025-06 conditional novelty 6.0 of 10

    An FPGA plus software frequency-mask trigger records CRES events with 96.7% data reduction and under 0.5% efficiency variation for the Project 8 Phase II neutrino mass experiment.

  4. Type-III Seesaw in Non-Holomorphic Modular Symmetry and Leptogenesis

    hep-ph 2025-08 unverdicted novelty 5.0 of 10

    A Type-III seesaw model based on non-holomorphic modular symmetry fits NuFIT 6.0 neutrino data and produces baryogenesis via leptogenesis with Y_B-L about 1e-9.
