CDF Logo Measurement of WZ and ZZ production in final states with b-tagged jets





We present a combined measurement of the production cross section of V Z (V = W or Z) events in final states containing charged leptons (electrons or muons) or neutrinos, and heavy flavor jets,using data collected by the CDF detector at the Fermilab Tevatron Collider. The analyzed samples correspond to 9.45 fb -1 of p+p-bar collisions at a center of mass energy of 1.96 TeV. Ass uming the ratio of the productio cross sections for WZ and ZZ as predicted by the standard model, we measure the total V Z crosssection to be 4.08 +1.38 -1.26 pb. This is consistent with the standard model prediction and corresponds to a significance of about 3.2 standard deviations above the background-only hypothesis.
