 +  
 +   <hidden TTP97-11  Mass Corrections to the Vector Current Correlator > Three-loop QCD corrections to the vector current correlator 
 + are considered.  The large momentum procedure is applied in order to 
 + evaluate mass corrections up to order $(m^2/q^2)^6$.  The inclusion of 
 + the first seven terms to the ratio 
 + $R=\sigma(e^+e^-\to\mbox{hadrons})/\sigma(e^+e^-\to\mu^+\mu^-)$ leads 
 + to reliable predictions from the high energy region down to relatively 
 + close to threshold.
