The PHLC2011 conference is underway with the promise of new reports from CMS and ATLAS using around 200/pb of data. The conference notes released by ATLAS so far suggest that only better exclusion limits will be found unless they are holding back some surprises. Today CMS have also shown their first paper using 190/pb from 2011 data. It also provides new exclusions.
From before the conference the main excitement came from the Tevatron where CDF have shown a 4-sigma bump at 150 GeV in decays producing W bosons and two jets. Dorigo remains firmly sceptical while Jester reports that detailed analysis of the events are consistent with a new particle just below 300 GeV that decays into a W-boson and the lighter unknown particle at 150 GeV. A study by D0 using similar data will be a crucial indicator of whether this effect is here to stay. They are expected to report on Friday at Fermilab.
Before then we will have a number of new search reports at PLHC2011, mostly on Thursday and Friday, but also today we have a special seminar from Jon Butterworth on behalf of ATLAS that just might have news (Update: It doesn’t).
So by the end of the week particle physics could look very different, and if it is all an anti-climax we just have to wait for the next big conference EPS-HEP2011 where at least 1000/pb of LHC data will be on show at the end of July. My betting is that will be the one to watch out for.
