Parity violation in atoms: neutrino-mediated long range forces and finite nuclear size
Mikhail Gorchtein, Hubert Spiesberger
We consider neutral-current parity-violating interactions in an atom mediated by the exchange of a neutrino-antineutrino pair. We explicitly account for the nuclear finite size enc…
Taming nuclear size and shape effects in superallowed beta-decay
Bingcheng He, Mikhail Gorchtein, Matthias Heinz +3
We present the first combined analysis of the statistical rate function f in superallowed beta decays with ab initio calculations and data. We focus on C10 to 10B, 14O to 14N and 2…
A hitchhiker's guide to nuclear polarization in muonic atoms
Mikhail Gorchtein
I consider the so-called nuclear polarization correction to the 1S-levels in light to intermediate muonic atoms. An easy to use recipe to compute it is given. The calculation inclu…
Cabibbo-Kobayashi-Maskawa unitarity deficit reduction via finite nuclear size
M Gorchtein, V Katyal, B Ohayon +2
We revisit the extraction of the CKM matrix element from the superallowed transition decay rate of AlMg, focusing on finite nuclear size effe…
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…
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…
