%0 Journal Article %T Weak Decays of Heavy Quarks %A Fulvia De Fazio %J Physics %D 2000 %I arXiv %X We review some aspects of weak decays of hadrons containing one heavy quark. The main emphasis is on $B$ physics, in particular in the framework of the Heavy Quark Effective Theory. %U http://arxiv.org/abs/hep-ph/0010007v2
