Abstract The QCD Sum Rules (QCDSR) method allows us to have an approximate treatment for non-perturbative effects in QCD. Using this technique one can obtain hadronic parameters from the underlying theory, namely QCD. The calculations involved are lengthy, with many Feynman diagrams and loops even at leading order (LO). As a consequence of this technical difficulty many recent QCDSR results are obtained only at LO and have considerable theoretical uncertainties. We intend to obtain next-to-leading (NLO) results for a few important calculations, with the aim of developing a systematic approach for the calculation of these corrections. We also intend to explore the possibility of applying recent advances in Generalized Unitarity methods to the QCDSR. (AU) | |
