Book excerpt: The authors present the first measurement of the ratio of branching fractions [Beta]([Lambda][sub 6] [yields] [Lambda][sub c][sup +] [mu][sup -][bar [nu]][sub [mu]])/[Beta]([Lambda][sub b] [yields] [Lambda][sub c][sup +][pi][sup -]) based on 171.5 pb[sup -1] of p[bar p] collisions at [radical]s = 1.96 TeV taken with the CDF-II detector. In addition, they present measurements of [Beta]([bar B][sup 0] [yields] D*[sup +] [mu][sup -][bar [nu]][sub [mu]])/[Beta]([bar B][sup 0] [yields] D*[sup +][pi][sup -]) and [Beta]([bar B][sup 0] [yields] D[sup +][mu][sup -][bar [nu]][sub [mu]])/[Beta]([bar B][sup 0] [yields] D[sup +][pi][sup -]), which serve as control samples to understand the data and Monte Carlo used for the [Lambda][sub b] analysis.
