Description
We present a measurement of the $Z \rightarrow b\bar{b}$ production cross section in $p\bar{p}$ collisions at $\sqrt s = 1.96 TeV$. We use a data set of 5.46 $fb^{-1}$ collected by the CDF experiment at the Tevatron collider during Run II using a dedicated trigger path which required a displaced vertex compatible with a b-hadron decay. A data-driven procedure is applied to estimate the dijet mass spectrum of the non-resonant multijet background. Using a similar strategy we set one of the most stringent upper limits on the production of a Higgs-like particle in association with b quarks. We also set a limit on the inclusive SM $H \rightarrow b\bar{b}$ .
