摘要: Pseudoscalar meson charge radii calculated in the PCAC soft-current limit approximation at triangle level are good agreement with data. The authors study whether or not removal of improves comparison between theory and experiment. No clear conclusion can be drawn as yet, but a slight improvement data will decide issue.
