Combined Results on b-Hadron Production Rates and Decay Properties

Combined results on b- hadronlifetimes, b- hadronproduction rates, B{sub d}{sup 0}-{bar B}{sub d}{sup 0} and B{sub s}{sup 0}-{bar B}{sub s}{sup 0} oscillations, the decay width difference between the mass eigenstates of the B{sub s}{sup 0}-{bar B}{sub s}{sup 0} system, the average number of c and {bar c} quarks in b- hadrondecays, and searches for CP violation in the B{sub d}{sup 0}-{bar B}{sub d}{sup 0} systemare presented. They have been obtained from published and preliminary measurements available in Summer 2000 from the ALEPH, CDF, DELPHI, L3, OPAL and SLD Collaborations. These results have been used to determine the parameters of the CKM unitaritytriangle.
