AnomalousWboson production at DESY HERA

We present the results of a complete tree level calculation for $W$ boson production processes $e^{-}\overrightarrow{p}{e}^{-}{\mu }^{+}{\nu }_{\mu }X$ and $e^{-}\overrightarrow{p}{e}^{-}{\mu }^{-}{\overline{\nu }}_{\mu }X$ introducing anomalous $\mathrm{WW}\gamma$ and $\mathrm{WWZ}$ couplings. Detailed results for the distributions of final state particles are obtained. In the region of small momentum transfer we calculate the contribution of hadronlike photon component in the structure function approach.
