Radiative corrections are essential for an accurate determination of $V_{u d}$ from superallowed 𝛽 decays. In view of recent progress in the single-nucleon sector, the uncertainty is dominated by […]
We calculate the 𝛽 spectrum in the decay of 6He using quantum Monte Carlo methods with nuclear interactions derived from chiral effective field theory and consistent weak vector and axial […]
Within a class of models in which lepton flavor violation is induced dominantly by scalar particle exchanges, we estimate the 𝜇→𝑒 conversion rate in several nuclei. We include next-to-leading order […]
Precision tests of first-row unitarity of the Cabibbo–Kobayashi–Maskawa matrix currently display two intriguing tensions, both at the 3σ level. First, combining determinations of Vud from superallowed β decays with Vus […]
We simulate a black hole accretion disk system with full-transport general relativistic neutrino radiation magnetohydrodynamics for 1.2 s. This system is likely to form after the merger of two compact […]
