Electroweak box diagram contribution for pion and kaon decay from lattice QCD

One of the sensitive probes of physics beyond the standard model is the test of the unitarity of the Cabbibo-Kobyashi-Maskawa (CKM) matrix. Current analysis of the first row is based on \(|V_{ud}|\) from fourteen superallowed \(0^+ \to 0^+\) nuclear \(\beta\) decays and \(|V_{ud}|\) from the kaon se...
