====== TTP95-03 QCD Corrections to the rho Parameter ======
 
 
   <hidden TTP95-03  QCD Corrections to the rho Parameter > The three-loop QCD corrections to the $\rho$ parameter from top and
 bottom quark loops are calculated.
 The result differs from the one recently calculated 
 by Avdeev et al. As function of the pole mass the numerical value is given by
 $\drho=\frac{3G_F M_t^2}{8\sqrt{2}\pi^2}(1- 2.8599\, \api 
 - 14.594\, (\api)^2 )$.
