The combination of the CDF and DZero results previously described individually are now available. The main result is that there is an exclusion from 158 GeV to 175 GeV. This means that the ranges left for a Higgs are from 114 GeV to 158 GeV or from 175 GeV to 185 GeV. This will be described at ICHEP this afternoon by Ben Kilminster.
As for the Higgs-plus-bottom channel, it shows an excess of just over 2 sigma in the range 130 GeV to 160 GeV. Very tantalising but also very inconclusive. A 2-sigma effect is normally regarded as no more than noise in the experimental physics community. They need 3-sigma to call it an “observation”, and 5-sigma to call it a “discovery”. This result is based on only 2 inverse femtobarns of data at one of the experiments. Why did they not show a combined result as they didi for the Higgs searches?
There is one last plot of interest that shows binned signals on a hypothesis of a Higgs at 115 GeV. This has a clear anomaly over two or three bins. Be wary to draw too many conclusions.
