Beyond Leading Logarithms in $g_V$: The Semileptonic Weak Hamiltonian at $\mathcal{O}(\hat{I}\pm \hat{I}{\pm }_s^2)$

Francesco Moretti, Martin Gorbahn, Sebastian Jaeger

We present the first next-to-leading-logarithmic QCD analysis of the electromagnetic corrections to the semileptonic weak Hamiltonian, including the mixed $\mathcal{O}(\hat{I}\pm \hat{I}{\pm }_s^2)$…
