 +      <hidden TTP09-17 ​ Reconstruction of heavy quark current correlators at O(&​alpha;<​sub>​s</​sub><​sup>​3</​sup>​) > We construct approximate formulas for the O(&​alpha;<​sub>​s</​sub><​sup>​3</​sup>​) QCD contributions to 
 + ​vector,​ axial-vector,​ scalar and pseudo-scalar quark current correlators,​ which are valid for 
 + ​arbitrary values of momenta and masses. The derivation  
 + is based on conformal mapping and the Pad&​eacute;​ approximation procedure and 
 + ​incorporates known expansions in the low energy, threshold and high energy 
 + ​regions. We use our results to estimate additional terms in  
 + these expansions.
