Everyone in the HEP community is breathlessly awaiting the release of results from the 2011 LHC run, expected to come at the EPS-HEP 2011 conference in Grenoble starting July 21. A public press conference has been announced for July 25. Presumably the new results will further tighten limits on supersymmetric particles, extra-dimensional models and other exotica, but the real excitement surrounds the question of what the news about the Higgs will be. The latest LHC data should finally allow competition on this front with the Tevatron.
Philip Gibbs at viXra log has posted here what looks like the bottom line for CMS. They are not yet able to exclude a Higgs at lower masses, including the range where the Tevatron has an exclusion region, but are able to exclude (at 95% confidence level) a SM Higgs in a higher mass region (about 275-425 GeV). This sort of result is not quite what it looks like, since precision electroweak measurements already rule out such a SM Higgs, and recall that the Higgs self-coupling increases with Higgs mass, meaning that one is entering into a region where one is not sure that perturbation theory applies. If the Higgs is not a weakly coupled field, life becomes much more complicated.
The source of the plot is variously described as “shown [July 8] at a seminar which as far as I know was public”, from “a public part of the CERN repository”, and “not yet public but was made accessible on a Fermilab site”.
ATLAS, the competition for CMS, presumably has a similar plot up its sleeve just about ready for release at EPS-HEP 2011. Once the two experiments have made public their independent results at this conference, they intend to immediately get to work producing a combined plot, with goal of releasing it at Lepton-Photon 2011, which will take place in Mumbai August 22-27.
