We give a brief overview of searches at TeV e^+e^- colliders for new particles that arise in models with extended gauge sectors. We concentrate on some recent developments in $W'$ searches and on leptoquark searches. We also briefly mention…
We discuss the production of new matter particles that are predicted by many extensions of the Standard Model, at future high--energy pp, eP and $e^+e^-$ linear colliders. We focus on the case of exotic, excited and di--fermions. Talk given…
The single production of leptoquarks in $e^+e^-$, $e\gamma$ and $\gamma \gamma$ linear colliders is discussed. We show that these new particles could be seen in such machines even if their mass is close to the kinematic limit. (Invited talk…
