Description
We present a search for technicolor particles decaying into $b\bar b$, $b\bar c$ or $b\bar u$ and produced in association with $W$ bosons in $p\bar p$ collisions at $\sqrt{s}= 1.96 \mathrm{TeV}$. The search uses approximately $1.9 \mathrm{fb}^{-1}$ of the dataset accumulated in the CDF II detector at the Fermilab Tevatron. We select events matching the $W$ + 2-jets signature and require at least one jets to be identified as $b$-quark jets. In the case of exactly one vertex $b$-tagged events, we apply a neural network flavor separator to reject contamination from charm and light quark jets. The number of tagged events and the invariant mass distributions of $W+2$ jets and dijets are consistent with the Standard Model expectations. We succeed to set a large 95% confidence level excluded region on the $π_{T}$ mass v.s. $ρ_{T}$ mass plane.
