Measurement of the Branching Fractions of Semileptonic Kaon Decays and Extraction of the CKM Parameter $\lvert V_{us} \rvert$
Semileptonic kaon decays $(K_{l3} = K^+ → π^0 l^+ \nu$ with $l = e, \mu)$ provide a clean way to extract the parameter $\lvert V_{us} \rvert$ of the Cabibbo-Kobayashi-Maskawa (CKM) quark mixing matrix. It is one of the fundamental parameters of the Standard Model and is only accessible via experimen...
