Jodi Cooley, the CDMS analysis coordinator and a professor from Southern Methodist University, will present the talk at SLAC at 2 p.m. PST, and Lauren Hsu, a scientist from Fermilab, will present the talk at Fermilab at 4 p.m. CST.

The result is important whether there is a discovery claim or not, and the CDMS collaborators might not want to give the honor of giving the first talk to only one person. <br /><br />To my mind (I am a competing experimentalist in the field), the CDMS behavior is consistent with either a positive (but low statistical significance) signal or just a factor of a few better limit. In either case, it is to CDMS's advantage to garner as much attention as possible prior to announcing the result, and to announce the result in a carefully planned, coherent manner. <br /><br />But if I were to bet, I would bet 5:1 that there are 2-3 events in the WIMP signal box. It's bound to happen occasionally when you are aiming for 0.5 background events, just from fluctuations from background (which are not necessarily only statistical). Remember that this is a blind search, and CDMS will feel obligated to report events in their WIMP acceptance box, even if they find after opening the box that their cuts weren't optimal for reaching 0.5 background events.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-2846514233477399562.post-16618271700337344312009-12-09T16:02:38.307+01:002009-12-09T16:02:38.307+01:00It could be that there is a Nature paper, it is ju...It could be that there is a Nature paper, it is just not imminent (I am parsing the Nature editor comments above).
