摘要：

We consider the possibility that the left-handed b-quark is a weak isospin singlet, instead of the usually assumed (t,b)L doublet assignment. Neutral current decays of the b serve as distinctive tests of this alternative; these tests are independent of the values of mixing parameters. Branching ratios of b→sℓ+ℓ- of 2% or b→dℓ+ℓ- of 1% are predicted. © 1979.
