The last* CLEO-c double tag event
(* last = last confidently-identified fully-reconstructed Ds Ds* event) CLEO-c stopped taking data earlier this week. We looked in the last data run (7:38 am to 8 am) of just over 61 thousand events...
View ArticleAn actual Higgs limit
News from ICHEP: Matt Herndon presented a new Tevatron combined limit for Higgs production. Thanks to a lot of hard work, good luminosity, and a bit of luck on D0’s part, CDF+D0 now exclude a Standard...

On Friday the LHC accelerator folk succeeded in injecting a proton beam into the LHC and taking it from Point 2 to Point 3 (one eighth the way around). I believe this is the first beam in the LHC...

A Friendly Reminder…
Your friendly local Geneva morning paper wishes to reassure you that CERN will not kill you on Wednesday. At any rate, we wouldn’t be making black holes tomorrow; there will be no colliding beams,...

Liveblogging the LHC turn-on festivities
It’s 9:03 am, and the propaganda informational film has just started… 9:05 – I’m here in the back row of the main auditorium, which is absolutely full. There are supposed to be two viewing rooms in...
View ArticleCDF multi-muons, hmm
So I’m way behind the bloggy curve on this one (e.g. here and here), but I thought I would at least read the paper before talking about it. The CDF collaboration (or two-thirds of it anyway) has...
