The expected Run II sensitivity can be easily extrapolated assuming the background will be dominated by b-rich events and the signal to noise ratio is not expected to improve substantially. The background is though irreducible in this channel, mainly due to QCD heavy flavor production. We do not find improved sensitivity for a counting significance limit.
More work is under progress.
Presently a Higgs dedicated multijet trigger is also under study. Below we provide links to plots with the Run I CDF results together with the extrapolation for Run II with several assumptions on luminosity, b-tag efficiencies and trigger efficiencies.
