Today brings news of two new experimental results, both consistent with the Standard Model:
- At the Higgs Hunting 2012 conference starting today, ATLAS reports results from the WW decay channel for the Higgs. At the July 4 joint announcement, CMS had reported results in this channel, but not ATLAS. Analyses of last year’s data had indicated fewer excess events in this channel than expected from a 125 GeV SM Higgs (see here). The 2012 data from CMS and ATLAS now show an excess in this channel of a size quite compatible with an SM Higgs. For more about this, and a nice summary of the latest combined data for various Higgs channels, see viXra log. The gamma-gamma channel Higgs signal is high, the tau-tau channel is low, others close to expected, but deviations from the SM predictions are not especially significant.
- At DarkAttack2012, Columbia’s Elena Aprile gave a talk this morning presenting new results from Xenon100. These show no evidence for a dark matter detection and provide the strongest exclusions yet of conjectural high mass WIMPs such as SUSY is supposed to provide. The Xenon100 results now rule out most of the region where pre-LHC CMSSM SUSY model fits showed a dark matter WIMP was supposed to be (see for instance slide 31 here).
Update: There’s a press release about the Xenon100 result here.
