We present a new value for the neutron lifetime of 878.5 +- 0.7 stat. +- 0.3 syst. This result differs from the world average value (885.7 +- 0.8 s) by 6.5 standard deviations and by 5.6 standard deviations from the previous most precise result. However, this new value for the neutron lifetime together with a beta-asymmetry in neutron decay, Ao, of -0.1189(7) is in a good agreement with the Standard Model.

Discussion (0). Continue with ORCID to comment.

  1. Vector-like quark doublets, weak-basis invariants and CP violation

    hep-ph 2024-12 conditional novelty 7.0 of 10

    Vector-like quark doublets allow CP violation in weak-basis invariants of mass dimension six; the resulting framework organizes the model's parameters, gives the complete CP-odd invariant set for one doublet, and link...

  2. Semi-invisible Hyperon Decays in the Effective Lagrangian Approach

    hep-ph 2026-06 unverdicted novelty 4.0 of 10

    Branching ratios for hyperon semi-invisible decays (hadronic ~10^{-5}, radiative <10^{-7}) are calculated with sizable one-loop corrections using effective Lagrangians.

  3. Effect of Dark matter and $\sigma$-cut potential on radial and non-radial oscillation modes in neutron stars

    astro-ph.HE 2025-07 conditional novelty 4.0 of 10

    Dark matter-admixed neutron stars oscillate at higher f- and p1-mode frequencies than ordinary or σ-cut models, while quasi-universal oscillation relations still hold.
