Instantons and the DeltaI = 1/2 rule.
N. I. Kochelev,V. Vento +1 more
TL;DR: In this paper, the instanton-induced interaction leads to a significant enhancement of the Ao weak amplitude determining the DeltaI = 1/2 rule, through the contribution of operators with dimension d = 9, as we show in the weak K--> pi(pi) decay.

Effective weak chiral Lagrangian from the instanton vacuum
TL;DR: In this article, the effective weak chiral Lagrangian from the instanton vacuum was studied and employed to derive the corresponding bosonic weak effective Lagrangians in leading order with the low-energy constants to be used, e.g., in chiral perturbation theory.

Regularization and Renormalization of Gauge Fields
Gerard 't Hooft,M.J.G. Veltman +1 more
TL;DR: In this article, a new regularization and renormalization procedure for gauge theories is presented, which is particularly well suited for the treatment of gauge theories and is transparent when anomalies such as the Bell-Jackiw-Adler anomaly may occur.

Consequences of anomalous ward identities
TL;DR: In this paper, the anomalous Ward identities are shown to satisfy consistency or integrability relations, which restrict their possible form, for the case of SU(3) × SU(1) and for SU(2) + SU (3) + 2.

Weak decays beyond leading logarithms
TL;DR: In this paper, the authors review the present status of QCD corrections to weak decays beyond the leading-logarithmic approximation, including particle-antiparticle mixing and rare and $\mathrm{CP}$-violating decays.

Computation of the quantum effects due to a four-dimensional pseudoparticle
TL;DR: In this paper, a detailed quantitative calculation is carried out of the tunneling process described by the Belavin-Polyakov-Schwarz-Tyupkin field configuration, where a certain chiral symmetry is violated as a consequence of the Adler-Bell-Jackiw anomaly.

Global Aspects of Current Algebra
TL;DR: In this paper, a new mathematical framework for the Wess-Zumino chiral effective action is described, and it is shown that this action obeys an a priori quantization law, analogous to Dirac's quantization of magnetic change.
