Genuine Dilatons in Gauge Theories
R. J. Crewther
A genuine dilaton allows scales to exist even in the limit of exact conformal invariance. In gauge theories, these may occur at an infrared fixed point (IRFP) t…
Status of Chiral-Scale Perturbation Theory
R. J. Crewther, Lewis C. Tunstall
Chiral-scale perturbation theory PT has been proposed as an alternative to chiral perturbation theory which explains the rule for kaon dec…
Quarks and Anomalies
R. J. Crewther
A nonperturbative understanding of neutral pion decay was an essential step towards the idea that strong interactions are governed by a color gauge theory for quarks. Some aspects…
Chiral-Scale Perturbation Theory About an Infrared Fixed Point
R. J. Crewther, Lewis C. Tunstall
We review the failure of lowest order chiral perturbation theory PT to account for amplitudes involving the resonance and extrap…
rule for kaon decays derived from QCD infrared fixed point
R. J. Crewther, Lewis C. Tunstall
This article gives details of our proposal to replace ordinary chiral perturbation theory PT by 3-flavor chiral-scale perturbation theory PT.…
Infrared Fixed Point in the Strong Running Coupling: Unraveling the ΔI=1/2 puzzle in K-Decays
R. J. Crewther, Lewis C. Tunstall
In this talk, we present an explanation for the Delta I = 1/2 rule in K-decays based on the premise of an infrared fixed point alpha_IR in the running coupling alpha_s of quantum c…
