TL;DR: In this article, the instanton contribution to the vacuum energy in supersymmetric Yang-Mills theories is considered and the exact beta function for n -extended supersymmetry is found.
723 citations
TL;DR: In this paper, a review of the theoretical interpretation of charmonium properties is given and a classification of the electromagnetic and strong decays are discussed, based on the assumption that the strong interaction between charmed quark and charmed antiquark in charmium is mediated by coloured gluons as described by Quantum Chromodynamics.
534 citations
TL;DR: In this paper, the mass scale intrinsic to the resonance structures in different channels is not universal; a large mass scale is discovered, for instance, in the 0 −, 0 + gluonic channels.
512 citations
TL;DR: In this paper, the main emphasis is put on gluon operators which appear in expansion of n-point functions induced by colourless quark currents, and two convenient schemes are discussed in detail: the abstract operator method and the method based on the Fock-Schwinger gauge.
Abstract: We review the technique of calculation of operator expansion coefficients. The main emphasis is put on gluon operators which appear in expansion of n-point functions induced by colourless quark currents. Two convenient schemes are discussed in detail: the abstract operator method and the method based on the Fock-Schwinger gauge for the vacuum gluon field. We consider a large number of instructive examples important from the point of view of physical applications.

TL;DR: In this article, a simple explanation is given why the instanton amplitude is exhausted by one loop whilst in the standard supergraph technique the effective action contains terms of all orders in the coupling constant and an exact relation between the Gell-Mann-Low function and the anomalous dimensions of matter superfields stemming from instanton calculus is presented.

TL;DR: In this paper, a systematic study is made of the non-perturbative effects in quantum chromodynamics, where the basic object is the two-point functions of various currents and the terms of this series are shown to be of two distinct types.
3,874 citations
TL;DR: In this article, the low energy representation of several Green's functions and form factors and of the na scattering amplitude are calculated in terms of a few constants, which may be identified with the coupling constants of a unique effective low energy Lagrangian.
3,277 citations
TL;DR: In this paper, the authors construct the generating functional of U(3)×U(3), which allows them to calculate the Green functions up to and including terms of order p4 (at fixed radio m quark p 2 ) in terms of a few coupling constants which chiral symmetry leaves undetermined.

TL;DR: A twisted version of four dimensional supersymmetric gauge theory is formulated in this paper, which refines a nonrelativistic treatment by Atiyah and appears to underlie many recent developments in topology of low dimensional manifolds; the Donaldson polynomial invariants of four manifolds and the Floer groups of three manifolds appear naturally.
Abstract: A twisted version of four dimensional supersymmetric gauge theory is formulated. The model, which refines a nonrelativistic treatment by Atiyah, appears to underlie many recent developments in topology of low dimensional manifolds; the Donaldson polynomial invariants of four manifolds and the Floer groups of three manifolds appear naturally. The model may also be interesting from a physical viewpoint; it is in a sense a generally covariant quantum field theory, albeit one in which general covariance is unbroken, there are no gravitons, and the only excitations are topological.

TL;DR: In this paper, a modification of the axion scheme which restores the natural P and T invariance of the theory cannot be ruled out experimentally and is based on the assumption that QCD resolves the U(1) problem, i.e., the mass of the singlet pseudoscalar meson does not vanish in the chiral limit.
