Abstract

We consider three broad classes of nonstandard models for b quark decay: (1) b → ℓℓq with charged or neutral leptons of arbitrary flavor; (2) b → ℓqq; and (3) b → qa- where a- is a Higgs boson or hyperpion. For these classes of models we have calculated the charged energy fraction and the inclusive yields of electrons, muons, protons, and lambdas. We demonstrate that these model predictions are inconsistent with CLEO measurements at the γ (4S).
