Purpose of tracking detectors with "stereo design"
HERA-B used silicon microstrip detectors for their vertex detector. Behind each two sided detector with strips in x- and y direction, a second identical detector was placed, rotated by 5 degrees. LHCb uses a similar design for the phi-detector...
I'm giving a report on the LHCb for a detector physics class. I don't quite understand how b-bbar-pairs are produced at the LHCb. LHCb collides two symmetric proton beams and is supposed to work as a b factory.
In many papers concerning the LHCb, for instance...
