LEP measurements of $V_{cb}$ using $B^{0} \to D^{*}^{+}l^{-}\nu$
CKM elements are free parameters to be measured. V/sub cb/ is the main CKM element allowing b decay. Its smallness accounts for the long b lifetime and our ability to observe higher order effects such as B oscillations. V/sub cb/ can be measured from the inclusive semileptonic decay rate of B hadron...
