Direct 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 کاملNonlocal Condensates and Current-current Correlators within the Instanton Liquid Model
The non-perturbative vacuum of QCD is densely populated by long wave fluctuations of gluon and quark fields. The order parameters of this complicated state are characterized by the vacuum matrix elements of various singlet combinations of quark and gluon fields, condensates: 〈: q̄q :〉, 〈 : F a μνF a μν : 〉 , 〈 : q̄(σμνF a μν λ 2 )q : 〉 , etc. The nonzero quark condensate 〈: q̄q :〉 is responsible f...
متن کاملVector and Axial - Vector Current Correlators within the Instanton Model of Qcd Vacuum
The pion electric polarizability, α E π ± , the leading order hadronic contribution to the muon anomalous magnetic moment, a hvp(1) µ , and the ratio of the difference to the sum of vector and axial-vector correlators, (V − A)/(V + A), are found within the instanton model of QCD vacuum. The results are compared with phenomenological estimates of these quantities following from the ALEPH and OPA...
متن کاملW6: Transcranial Direct Current Stimulation Workshop
It is an Intensive 1-day course for introducing utilizing transcranial direct current stimulation (tDCS) in an applied format. This technique is a noninvasive brain stimulation that uses direct electrical currents over the head to stimulate specific parts of the brain which modulates neuronal activity. It has strong potentiality in the field of medical and neuroscientific research. Anodal stimu...
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 ...
