Strongly-interacting Electroweak Sector At e-e- Colliders

We study the possible experimental signatures resulting from a strongly-interacting electroweak sector at $e^{-}{e}^{-}$ colliders, emphasizing the signal enhancement by high beam polarization. We also discuss the unique role for operating the collider in $e^{-}\gamma$ mode to produce a heavy isosinglet vector state ${\omega }_T$.
