摘要

We investigate the possibilities of probing γWW couplings through W → γff′ by computing the branching ratios for various polarization channels of W and γ, allowing for the most general γWW couplings. The bounds on the possible deviations of γWW couplings from their standard model values can be improved if the branching ratios for the decays of W's with positive and negative helicities can be separately measured.
