Abstrak

We analyse the so-called violations of quark-hadron duality in Finite Energy Sum Rules (FESRs) with the LR correlator, through the study of the possible high-energy behavior of the LR spectral function, taking into account all known short-distance constraints and the experimental tau-decay data. In particular we show that the use of pinched weights (PWs) allows to determine with high accuracy the dimension six and eight contributions in the Operator-Product Expansion, O 6 = ( − 4.3 − 0.7 + 0.9 ) ⋅ 10 − 3 GeV 6 and O 8 = ( − 7.2 − 5.3 + 4.2 ) ⋅ 10 − 3 GeV 8 [M.
