The Hadron Collider Physics Symposium will be next week in Kyoto, with announcements of new results from the LHC, some details of which are starting to trickle in. Chris Quigg explains what to look for here.
The LHC has just recently passed the milestone of 20 fb-1 of data at 8 TeV this year. Perhaps this will get up to 25 fb-1 by the end of this run later this year. After a heavy ion run early next year the machine will go into a long shutdown (until late 2014) for repairs to allow operation at close to design energy (probably at 13 TeV). Next week results will be reported based on 12 fb-1 (CMS) and 13 fb-1 (ATLAS) of this year’s 8 TeV data (compare to this past summer’s results based on 5.3 fb-1 (CMS) and 5.9 fb-1 (ATLAS)). Expect results from the full 2012 data at Moriond in March, with an official combination of results from the two experiments next summer.
On Monday LHCb will report the latest results on B(s)->mu+mu-, and the latest Higgs news should come at the Higgs parallel session on Wednesday. There will also be quite a few new, stronger limits on SUSY.
I’m hearing that these new results already can rule out the idea that this new particle is a pseudo-scalar. There will be no confirmation of an unexpectedly high gamma-gamma rate. Some excesses in the tau-tau channel are being seen, of roughly the size you would expect for a SM Higgs. So, all in all, things are still consistent with a SM Higgs. If not, please let me know….
Update: The B(s)->mu+mu- results from LHCb are out (see here), providing good agreement with the SM, and new, strong limits on possible SUSY models (see the last slide). More from Matt Strassler and Michael Schmitt.
For another source for new LHC results, together with interpretation of their signficance, the Chicago 2012 Workshop on LHC Physics is starting today.
