ATLAS just issues the latest release of its e-news, officially announcing the first W boson candidate events in the LHC … which of course reminds me of my nice little master thesis on the W mass measurement at ATLAS.
Below are illustrations of the two candidates: one W decaying into an electron (left) and one into a muon (right), of course both accompanied by the according neutrino, represented by missing energy (ETmiss) in the event.
For all of you interested in an Update on the Large Hadron Collider, the current Director General of CERN Prof. Dr. Rolf-Dieter Heuer will give a talk at Urania Berlin on Monday, April 26th at 19h00.
Woooh … I just made it into the news on a local TV station (for three seconds about two minutes into the video, only in the background, though)! Here’s the video link. Great isn’t it …
Almost as cool as my interview with a local newspaper last week … though the quote is not actually mine, the experiment is called ATLAS and not Astra and Thomas is not my Professor and … well whatever!
Time has come! We finally saw the first events at 7 TeV centre of mass energy … more will come!
Here’s an event display of one of the first events recorded in ATLAS today.
[Update Mar 30th]Euphoria is slowly settling now, after the first successful LHC fill with collisions at 7 TeV has ended. The press has left Zeuthen already a while ago and the inauguration of our little control room ended with trays of empty champagne bottles … seems like a pretty successful day![Update]
Seems like the re-start of the LHC will be celebrated with a little press conference in our new remote control room at DESY in Zeuthen next Tuesday … which I will join, of course ;)
Let’s see what’s going to happen …
[Update Mar 28th] CERN has set up a Live Webcast from 8h30 to 18h15 on Tuesday! [Update]
