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 $S U (3)_{L} \times S U (3)_{R}$ perturbation theory $χ$ PT $_{3}$ to account for amplitudes involving the $f_{0} (500)$ resonance and $O (m_{K})$ extrap…
