A New Twist on $Z \to b {\bar b}$

High Energy Physics - Phenomenology 2007-05-23 v1

Abstract

A new mechanism is proposed to explain the "anomaly" in ZbbˉZ \rightarrow b {\bar b} resulting in a prediction of a new, non-sequential fourth family whose masses could all be below MWM_W, thus opening up an exciting porpect for near-future discoveries at LEP2 and possibly at the Tevatron.
