Resumen/Abstract
We combine the results of searches for the standard model (SM) Higgs boson based on the full CDF Run II data set obtained from √s=1.96  TeV p¯p collisions at the Fermilab Tevatron corresponding to an integrated luminosity of 9.45  fb−1. The searches are conducted for Higgs bosons that are produced in association with a W or Z boson, have masses in the range 90–150  GeV/c2, and decay into b¯b pairs. An excess of data is present that is inconsistent with the background prediction at the level of 2.5 standard deviations (the most significant local excess is 2.7 standard deviations).
