Anomalous commutator corrections to sum rules.
In this paper we consider the contributions of anomalous commutators to various QCD sum rules. Using a combination of the BJL limit with the operator product expansion the results are presented in terms of the vacuum condensates of gauge invariant operators. It is demonstrated that the anomalous contributions are no negligible and reconcile various apparently contradictory calculations.
متن کاملEvaluation of the Axial Vector Commutator Sum Rule for Pion-Pion Scattering
We consider the sum rule proposed by one of us (SLA), obtained by taking the expectation value of an axial vector commutator in a state with one pion. The sum rule relates the pion decay constant to integrals of pion-pion cross sections, with one pion off the mass shell. We remark that recent data on pionpion scattering allow a precise evaluation of the sum rule. We also discuss the related Adl...
متن کاملEqual Sum Subsets : Complexity of
We start an investigation into the complexity of variations of the Equal Sum Subsets problem, a basic problem in which we are given a set of numbers and are asked to nd two disjoint subsets of the numbers that add up to the same sum. While Equal Sum Subsets is known to be NP-complete, only very few studies have investigated the complexity of its variations. In this paper, we show NP-completenes...
متن کاملA Multiple Commutator Formula for the Sum of Feynman Diagrams
In the presence of a large parameter, such as mass or energy, leading behavior of individual Feynman diagrams often get cancelled in the sum. This is known to happen in large-Nc QCD in the presence of a baryon, and also in the case of high-energy electron-electron as well as quark-quark scatterings. We present an exact combinatorial formula, involving multiple commutators of the vertices, which...
متن کاملQcd Sum Rule Approach
In these lectures, I describe the techniques used within the QCD sum rule approach. The basic concepts of the approach are introduced using a simple model of quantum-mechanical oscillator in 2+1 dimensions. Then I discuss their field-theoretical extension and the construction of the operator product expansion for current correlators in QCD. The calculation of static parameters is illustrated on...
