Examining Collision Events

Inside CMS, people are busy learning what they can from the handful of collision events recorded yesterday. Our magnet was not on at the time because it would have interfered with the beams, at this early stage, so we cannot understand anything about charged track momenta. But those straight-line tracks still provide a testing ground for several key aspects of event reconstruction.

Since I am a loyal member of the CMS Collaboration, I won’t divulge here any details about what my colleagues are doing, but I will say that I am very impressed by what I see. Stay tuned – public presentations are scheduled in a matter of days…
