Abstract
Our aim is to test a model recently presented, motivated by the reported Rb and Rc "crisis", which contains extra vector fermions. We suggest an alternative indirect test of the possible existence of new heavy quark flavors at the LEP2 collider, which turns out to give the clearest signal. We calculate [Formula: see text] cross-sections within this framework, including one-loop corrections, and find measurable differences compared to the Standard Model predictions.
