Abstract
An analysis is presented measuring the inclusive kaon and proton rates in B decay products to be BT(B --> KX) = 0.683 +/- 0.021 +/- 0.020 and BT(B --> pX) = 0.142 +/- 0.018 +/- 0.019. A measurement of the Ab semileptonic form factor is also presented. The slope parameter is found to be (p) over cap (2) = 1.7 +/- 1.3 +/- 0.6. Including the absolute event rate in the fit, th e value (p) over cap (2) = 1.65 +/- 0.60 +/- 0.55 was obtained.
