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 proper – they’ve put beam into the injection lines before, but not into the ring. From what I can find they got it to work on the first try. A promising sign of things to come? (We are promised a beam all the way around on September 10.)

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 Model Higgs at 170 GeV at exactly 95% confidence level. (Note: not at 165 or 175. It’s a very small exclusion window.) The talk will be available later in the evening.
UPDATE: as promised, available here (Sun 15:30).
