Ratios of $W^{\pm }\gamma$ and $Z\gamma$ Cross Sections: New Tools in Probing the Weak Boson Sector at the Tevatron

U. Baur, S. Errede, J. Ohnemus

The ratios ${\mathcal{R}}_{\gamma ,\ell }=B(Z\to {\ell }^{+}{\ell }^{-})\cdot \sigma (Z\gamma )/B(W\to \ell \nu )\cdot \sigma (W^{\pm }\gamma )$, ${\cal R}_{γ, ν}= B(Z\to\barνν)\cdotσ(Zγ)/\allowbreak B(W\to\ellν)\cdotσ(W^ \p…
