New probes of anomalous $WW\gamma$ couplings at future $e^{+}{e}^{-}$ linacs

Abstract

We investigate the sensitivity of single photon plus missing energy cross-sections at future $e^{+}{e}^{-}$ linacs to non-standard $WW\gamma$ couplings. We show that even with conservative estimates of systematic errors there is still considerable sensitivity to anomalous couplings. Analytic expressions for helicity amplitudes are presented.
