Shifting $R_b$ with $A^b_{FB}$

Precision measurements at the $Z$ resonance agree well with the standard model. However, there is still a hint of a discrepancy, not so much in $R_{b}$ by itself (which has received a great deal of attention in the past several years) but in the forward-backward asymmetry $A_{F B}^{b}$ together with $R_{b}$ . The two are of course correlated. We explore the possibilty that these and other effects are due to the mixing of $b_{L}$ and $b_{R}$ with one or more heavy quarks.
