Final Results on Heavy Quarks at LEP and SLD

Abstract

In the last decade, the LEP and SLD experiments played a central role in the study of B hadrons (hadrons containing a b quark). New B hadrons have been observed ($B_s^0$, \Lambda_b$,$\Xi_b$and$B^{**}$)andtheirproductionanddecaypropertieshavebeenmeasured.InthispaperwewillfocusonmeasurementsoftheCKMmatrixelements:$|V_{cb}|$,$|V_{ub}|$,$|V_{td}|$and$|V_{ts}|$. We will show how all these measurements, together with theoretical developments, have significantly improved our knowledge on the flavour sector of the Standard Model.
