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