Status of the CKM Matrix

Abstract

The experimental status and theoretical uncertainties of the Cabibbo--Kobayashi--Maskawa (CKM) matrix describing the charge-changing weak transitions between quarks with charges -1/3 ($d,s,b$) and 2/3 ($u,c,t$) are reviewed. Some recent methods of obtaining phases of CKM elements are described.
