The Cabibbo-Kobayashi-Maskawa (CKM) matrix describes the flavor mixing among the quarks and the amount of CP violation through its single nontrivial phase. Thus, precise determinations of the CKM matrix elements are essential to test the standard model. This paper presents an improved measurement of /Vcb/, the coupling of the b quark to the c quark.
