Description
With nominal collision energies of 14 TeV at luminosities of 10^34
cm^-2 s^-1, the LHC will explore energies an order of magnitude higher
than colliders before. This poses big challenges for the tracking
system and the tracking software to reconstruct tracks in the primary
collision and the ~20 underlying events.
CMS has built a full silicon tracking system consisting of an inner
pixel detector and an outer strip detector with over 200 m^2 of active
area and over 70 million readout channels. The tracking software for
the CMS tracking system has to master the dense environment in LHC
collisions and also take into account multiple scattering. On average,
a track has to transverse 13 layers of the silicon tracker.
An overview of the tracking system and the tracking software will be
given. Both general and specialized tracking algorithms covering for
example electron reconstruction will be discussed.
To prepare for the start of data taking expected at the end of 2007,
CMS is conducting extensive cosmics tests with the tracking detector
outside of the collision hall. An overview of the preliminary results
of cosmic muon reconstruction with the CMS tracker using some of the
previously described algorithms will be given.
