On the statistical treatment of the Cabibbo angle anomaly
Abstract We point out that testing the equality of the Cabibbo angle as extracted from Γ(K → πlν), the ratio Γ(K → lν)/Γ(π → lν) and nuclear β decays is not identical to a test of first row unitarity of the Cabibbo-Kobayashi-Maskawa (CKM) matrix. The reason is that a CKM unitarity test involves only...
