First unitarity-independent determination of the CKM matrix elements $V_{td}$, $V_{ts}$, and {V_{tb} and the implications for unitarity

Abstract

The magnitudes of the CKM matrix elements $V_{td}$, $V_{ts}$, and $V_{tb}$ are determined for the first time without any assumptions of unitarity. The implications for the unitarity of the CKM matrix as a whole are discussed.
