The Pion-Nucleon Sigma Term and the Goldberger-Treiman Discrepancy

James V. Steele, Hidenaga Yamagishi, Ismail Zahed

The pion-nucleon sigma term is shown to be equal to the Goldberger-Treiman discrepancy at tree level. Its value estimated this way is very sensitive to the pion-nucleon coupling co…

Master Formula Approach to $γ γ \to π π$ processes

S. Chernyshev, I. Zahed

We analyze the $γ γ \to π^{0} π^{0}$ and $γ γ \to π^{+} π^{-}$ reactions using the master formula approach to chiral symmetry breaking. The pertinent vacuum correlators are estimated at tree lev…

BRST Quantization, Strong CP Violation, the U(1) Problem and $θ$ Vacua

Hidenaga Yamagishi, Ismail Zahed

The non-perturbative implications of BRST quantization are examined for $θ$ vacua and related issues. Strong CP violation is shown to be absent for QCD in the BRST formalism. Previ…
