Higher moments of heavy quark correlators in the low energy limit at O(αs2)

We present the first 30 moments of the low energy expansions of the vector, axial-vector, scalar and pseudo-scalar heavy quark correlation functions at three-loop order, including the singlet contribution which appears for the first time at three loops. In addition we compare the behavior of the moments for large n with the prediction from threshold calculations. (C) 2008 Elsevier B.V. All rights reserved.
