Color-Singlet Technipions at the Tevatron

Abstract

I discuss production and detection at the Tevatron $\pbarp$ collider of pairs of light ($\mpi = 100$--$200\,\gev$) color--singlet technipions that are expected in all nonminimal models of technicolor. Gluon fusion production rates can be as large as $\CO(1\,\pb)$. Topcolor--assisted technicolor is required to prevent top quarks from decaying as $t \ra \tpip b$. An intriguing consequence of this is that the decays $\tpip \ra τ^+ ν_τ$, $c \ol s$ and $\tpiz \ra b \ol b$ may also be suppressed so that $\tpip \ra W^+ γ$ and $\tpiz \ra γγ$ are significant. These modes have spectactular signatures at the Tevatron.
