# {Search for third generation vector leptoquarks in $p\bar{p}$ Collisions at $\sqrt{s}$ = 1.96-TeV}

We search for a third generation vector leptoquark (VLQ3) that decays to a $b$ quark and tau lepton using the CDF II detector and 320 pb-1 of integrated luminosity from the Fermilab Tevatron. Observing a number of events in agreement with standard model expectations, we obtain, assuming Yang-Mills (minimal) couplings, the most stringent upper limit on the VLQ3 pair production cross section of 344 fb (493 fb) and lower limit on the VLQ3 mass of 317 GeV/c2 (251 GeV/c2) at 95% C.L.
