Nuclear Physics Seminar

The CMS detector consists of a 13 m long, 6 m wide superconducting
solenoid providing a uniform 4 T magnetic field. Charged particles
will be measured with a large acceptance, high resolution silicon
tracker consisting of pixel and strip detector layers. The tracker is
surrounded by electromagnetic and hadronic calorimeters located inside
the magnet while the muon detector is outside. The central detector
will be complemented by CASTOR and a ZDC. The tracking system and the
muon detector provide hermetic coverage for particles with |eta| <
2.5. The high granularity, high resolution calorimeters will provide
hermetic coverage for |eta| < 7. The CMS data acquisition system, with
its reliance on a multipurpose, high-level trigger system, is uniquely
qualified for efficient triggering in high-multiplicity heavy ion
events. The CMS detectors will allow a wide range of unique
measurements in nuclear collisions. The excellent calorimeters
combined with tracking will allow detailed studies of jets,
particularly medium effects on the jet fragmentation function and the
energy and pT redistribution of particles within the jet. The large
CMS acceptance will allow detailed studies of jet structure in rare
jet-gamma and jet-Z0 events. The high resolution tracker will tag b
quark jets. The muon chambers combined with tracking will study
production of the Z0,J/psi and the epsilon family in the central
rapidity region of the collision. In addition to the detailed studies
of hard probes, CMS will measure charged multiplicity, energy flow and
azimuthal asymmetry event-by-event. We will present the latest status
of CMS preparations for LHC startup as well as the detailed studies of
the CMS capabilities using the full detector simulation and
reconstruction.
