====== TTP97-11 Mass Corrections to the Vector Current Correlator ======
 
 
   <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.
