| dc.description | The formalism for extracting the CKM parameter $V_{cd}$ from $νN$ production of charm is discussed in some detail. The various model assumptions needed are clearly pointed out. A direct determination from neutrino induced dimuon production requires $νN$ charm production data, $% νN$ charm hadronization data, and the semi-muonic branching ratios for charmed hadrons. Hadronization data from FNAL E531 is re-analyzed to take advantage of better-determined properties of the charmed hadrons. A small bias in the original published result is removed. Neutrino induced charm fragmentation is compared to $e^{+}e^{-}$ charm fragmentation functions; the data are consistent with a common hadronization scheme. An updated value of the mean semi-muonic branching ratio for charmed hadrons produced in $νN$ scattering for $E_ν>30$ GeV is obtained. This value is used to determine $% V_{cd}$ and its associated uncertainties. Prospects for improving the $% V_{cd} $ measurement to test the unitarity limit of the CKM matrix are described. | |
