CMS Muons in 7 TeV Collisions
March 30, 2010 at 7:02 am 2 comments
It is an exciting day, with thousands of 7 TeV collision events flowing in. I watched the frustrating first failures from my laptop at home, in the middle of the night. Now that the sun is up, the scenario is much brighter – CERN just held a press conference in which the Steve Myers and the leaders of the four LHC experiments proudly and joyfully showed that they are taking data.
Here is a pretty event from my own experiment, CMS, in which a clean muon track is reconstructed well:
The muon is the long red track the curves down to the lower right-hand corner. It has been detected and reconstructed in the Cathode Strip Chambers (CSCs), and my group at Northwestern belongs to the CSC group within CMS. So I am pleased and proud to see this nice event!
Edgar Carrera posted a different CMS event at US LHC Blog, where you can also see events from ATLAS.
The official CMS Press Release, in several world languages, is available here.

Nice! I really like the event display style.
Are you in CMS allowed to show live real-time event displays? In ATLAS this is not allowed – but for reasons I’m not clear on. So we can’t have a live-event display the way we do for the fermi machines.

Hi Gordon!
no, we are cautioned to post only displays that have been approved. Since the approval happens quickly, however, this is not a real hindrance. When it comes to real physics, such as a J/psi candidate, one would have to be more careful.
I suspect that real-time event displays will become common later on, perhaps after summer conferences (ICHEP).
