O ( α 2 s ) Corrections to Current Correlators ∗
In this contribution three-loop QCD corrections to current correlators are considered. The application of the large momentum procedure, which provides a systematic expansion in (m/q), allows the computation of terms up to n = 6 for the vector and axial-vector correlator and up to n = 4 for the scalar and pseudo-scalar correlator. Some physical applications are discussed. There are plenty of imp...
متن کامل1/Nc and 1/n preasymptotic corrections to Current-Current correlators
We obtain the corrections in 1/n and in 1/ lnn (n is the principal quantum number of the bound state) of the decay constants of scalar and pseudoscalar currents in two and four dimensions in the large Nc. We obtain them from the operator product expansion provided a model for the large n mass spectrum is given. In the two-dimensional case the spectrum is known and the corrections obtained in th...
متن کاملDirect Instanton Effects in Current-Current Correlators
We compute the effect of small-size instantons on the coefficient function of the chiral condensate in the operator product expansion of current-current correlators. Furthermore, we also compute the instanton corrections associated with four-quark and six-quark operators in the factorization approximation. We discuss the phenomenological implications of our result. CERN-TH.7483/94 IFUM 483/FT N...
متن کاملHints on the power corrections from current correlators in x - space
We consider an interpretation of the recent lattice data on the current-current correlators in the xspace. The data indicate rather striking difference between (axial)vector and (pseudo)scalar channels which goes beyond the predictions of the standard non-perturbative models. We argue that if the difference is to be explained by power corrections, there is a unique choice of the form of the cor...
متن کاملCurrent Correlators and AdS/CFT Geometry
We consider current-current correlators in 4d N = 1 SCFTs, and also 3d N = 2 SCFTs, in connection with AdS/CFT geometry. The superconformal U(1)R symmetry of the SCFT has the distinguishing property that, among all possibilities, it minimizes the coefficient, τRR of its two-point function. We show that the geometric Z-minimization condition of Martelli, Sparks, and Yau precisely implements τRR ...
