We analyze the Zff vertex in the framework of models that add a new bottom quark in a non-sequential way and we evaluate the tree level contribution to the LEP/SLC observables Γ[sub Z], R[sub b] and R[sub l]. We obtain bounds for the mixing angles from the experimentally allowed contour regions of the parameters Λ[sub L,R] introduced here. In order to get a more restrictive region, we consider the experimental results for B → vvX as well. [ABSTRACT FROM AUTHOR] |
