   <hidden TTP06-15  Four-loop moments of the heavy quark vacuum polarization function in perturbative QCD > New results at four-loop order in perturbative QCD for the first two
 Taylor coefficients of the heavy quark vacuum polarization function
 are presented. They can be used to perform a precise determination of
 the charm- and bottom-quark mass. Implications for the value of the
 quark masses are briefly discussed.
