Abstract.

We investigate the sensitivity of the semileptonic processes \(e^+e^-\to\ell^-\bar{\nu}_\ell\; q\; \bar q^\prime \), \(\ell=e\;\mbox{or}\;\mu\), on the non-standard trilinear gauge couplings, using the optimal observables method at Linear Collider energies. Our study is based on the four-fermion generator ERATO. Taking into account all possible correlations between the different trilinear gauge coupling parameters, we show that they can be measured with an accuracy of \(10^{-3}\) to \(10^{-4}\) for typical Linear Collider energies and luminosities.
