New shell-model calculations of the ${\delta }_C$ correction to superallowed $0^{+}\to 0^{+}$ nuclear $\beta$ decay and standard-model implications

Refined calculations of the radial mismatch correction, ${\delta }_{C2}$, to superallowed $0^{+}\to 0^{+}$ nuclear $\beta$ decay are performed using the shell model with realistic Woods-Sax…
