Search for Extra Gauge Bosons in Little Higgs Models at a Linear Collider

A generic feature of little Higgs models is presence of extra neutral gauge bosons. In the littlest Higgs model, the neutral extra gauge boson A H is lightest among the extra particles and could be as light as a few hundred GeV, which may be produced directly at an e + e − linear collider. We study production and decay of A H at the linear collider and… (More)
