Should the Europeans Give Up?

The European HEP community is now engaged in a “Strategy Update” process, the next step of which will be an open symposium this May in Granada. Submissions to the process were due last month, and I assume that what was … Continue reading

Short Items

The Fermilab Physics Advisory Committee recently recommended that the Tevatron be kept running for an additional three years (until 2014). By the end of that time it should be able to accumulate a total of 20 fb-1 of data, which … Continue reading

The End of LHC Run 2 and the Road Ahead

Some experimental HEP news items: Since 2015 the LHC experiments have been taking data from proton-proton collisions at 13 TeV. This is “Run 2” of the LHC, “Run 1” was at the lower energy of 8 TeV. The proton-proton Run … Continue reading

A 125-126 GeV Higgs?

Some more detail on Higgs rumors I’ve been hearing recently. Evidently the latest ATLAS data shows an excess in the gamma-gamma channel around 126 GeV, of the size expected if the Higgs is there, and CMS is also seeing an … Continue reading

This Week’s Rumor

A commenter on the previous posting has helpfully given us the abstract of an internal ATLAS note claiming observation of a resonance at 115 GeV. It’s the sort of thing you would expect to see if there were a Higgs … Continue reading

The Higgs Discovery

Just got out of 8 days in the Grand Canyon which was spectacular, Reliable rumors couldn’t wait, and they indicate that the experiments are seeing much the same thing as last year in this year’s new data: strong hints of … Continue reading

New LHC Results

This week results are being presented by the LHC experiments at the Moriond (twitter here) and Aspen conferences. While these so far have not been getting much publicity from CERN or in the media, they are quite significant, as first … Continue reading

A New 30 GeV Particle?

Last night a preprint appeared on the arXiv, with a re-analysis of old 1992-5 LEP data, looking at the dimuon spectrum for b-tagged (identified as involving a b-quark) events. An excess around 30 GeV was found, which would indicate a … Continue reading

WIMPs on Death Row

One of the main arguments given for the idea of supersymmetric extensions of the standard model has been what SUSY enthusiasts call the “WIMP Miracle” (WIMP=Weakly Interacting Massive Particle). This is the claim that such SUSY models include a stable … Continue reading
