Performance of the combined zero degree calorimeter for CMS

The combined zero degree calorimeter (ZDC) is a combination of sampling quartz/tungsten electromagnetic and hadronic calorimeters. Two identical combined calorimeters are located in the LHC tunnel at CERN at the straight section ~140 m on each side of the CMS interaction vertex and between the two beam pipes. They will detect very forward photons and neutrons. ZDC information can be used for a variety of physics measurements as well as improving the collision centrality determination in heavy-ion collisions. Results are presented for ZDC performance studies with the CERN SPS H2 test beam.

Protons, Deuterons and Flow

Proton and deuteron m_T spectra and rapidity densities at y=1.9-2.3 are presented for central SS, SPb and PbPb collisions. The inverse slopes increase with system size and mass. The radius parameter, R_G, extracted from ratios of the spectra increases with system size. R_G is proportional to 1/\sqrt{m_T} consistent with transverse flow and NA44's HBT results.
