LHC at the High Energy Frontier

A few minutes ago, one of the beams of the LHC was ramped up to an energy of 1180 GeV, besting the Tevatron’s top beam energy of 980 GeV. Update: Actually the beam was lost at 1040 GeV, which is … Continue reading

Higgs Escapes Part of Exclusion Region

This past winter a combined analysis of data from the two Tevatron experiments showed at 95% confidence level that the Higgs mass could not be in the range 160-170 GeV. This was a better result than expected: statistically the experiments … Continue reading
