Can a light technipion be discovered at the Tevatron if it decays to two gluons?
Abstract
In multiscale and topcolor-assisted models of walking technicolor, light, spin-one technihadrons can exist with masses of a few hundred GeV; they are expected to decay as rhoT -> W piT. For technirho masses ~200 GeV and technipion masses ~100 GeV, the process pbar p -> rhoT -> W piT has a cross section of about a picobarn at the Tevatron. We demonstrate the detectability of this process with simulations appropriate to Run II conditions, for the challenging case where the technipion decays dominantly into two gluons.
