+====== TTP97-52 Corrections of O(\alpha\alpha_s) to the Decay of the Z Boson into Bottom Quarks ======
+   <hidden TTP97-52  Corrections of O(\alpha\alpha_s) to the Decay of the Z Boson into Bottom Quarks > For the vertex corrections to the partial decay rate
+ $\Gamma(Z\to b\bar{b})$ involving the top quark only the leading terms
+ of order $\alpha\alpha_s$ in the $1/M_t$ expansion are known.  In this
+ work we compute the missing next-to-leading corrections. They turn out
+ to be equally important as the leading term and therefore have to be
+ included into an ${\cal O}(\alpha\alpha_s)$ analysis to arrive at
+ reliable predictions.
