Short Items

Posted on September 17, 2010 by woit

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 →

A 125-126 GeV Higgs?

Posted on December 2, 2011 by woit

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

Posted on April 21, 2011 by woit

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 →

A New 30 GeV Particle?

Posted on October 21, 2016 by woit

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

Posted on July 21, 2016 by woit

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 →
