W ANOMALOUS MOMENTS AND THE POLARIZATION ASYMMETRY ZERO IN gamma e --> W nu

Stanley J. Brodsky, Thomas G. Rizzo, Ivan Schmidt

We show from general principles that there must be a center of mass energy, ${\sqrt{s}}_0$, where the polarization asymmetry $A=\Delta \sigma (\gamma e\to W\nu )/\sigma (\gamma e\to W\nu )$ for circularly-polar…
