Testing for isospin symmetry breaking with extensive calculations of isotope shift factors in potassium
Vaibhav Katyal, A. Chakraborty, B. K. Sahoo +4
Precise evaluation of the isotope shift (IS) factors for seven low-lying potassium (K) states is achieved using relativistic coupled-cluster (RCC) theory. The energies of these sta…
Simultaneous Extraction of the Weak Radius and the Weak Mixing Angle from Parity-Violating Electron Scattering on
Matteo Cadeddu, Nicola Cargioli, Jens Erler +4
We study the impact of nuclear structure uncertainties on a measurement of the weak charge of at the future MESA facility in Mainz. Information from a large varie…
An strategy for taming nuclear-structure dependence of extractions: the superallowed transition
Michael Gennari, Mehdi Drissi, Mikhail Gorchtein +2
We report the first \textit{ab initio} calculation of the nuclear-structure-dependent radiative correction to the $ {}^{10}\mathrm{C} \rightarrow {}^{10}\mat…
Lattice QCD Calculation of Electroweak Box Contributions to Superallowed Nuclear and Neutron Beta Decays
Peng-Xiang Ma, Xu Feng, Mikhail Gorchtein +5
We present the first lattice QCD calculation of the universal axial -box contribution to both superallowed nuclear and neutron beta decays. This contribut…
Superallowed nuclear beta decays and precision tests of the Standard Model
Mikhail Gorchtein, Chien Yeah Seng
For many decades, the main source of information on the top-left corner element of the Cabibbo-Kobayashi-Maskawa quark mixing matrix were superallowed nuclear beta decays…
