Tracking and Primary Vertex Results in First 7 TeV Collisions

After a previous run at lower energies, the first 7 TeV proton-proton collisions produced by the LHC have been recorded by the CMS experiment in 2010. We use the silicon tracking detector and the 3.8~T superconducting solenoid to reconstruct the trajectories, momenta and vertexes of charged particle...

Sumario:After a previous run at lower energies, the first 7 TeV proton-proton collisions produced by the LHC have been recorded by the CMS experiment in 2010. We use the silicon tracking detector and the 3.8~T superconducting solenoid to reconstruct the trajectories, momenta and vertexes of charged particles. We report on the performance of this track, vertex, and beam line reconstruction for the first time at these higher beam energies.
