Simulation of Beam Halo and Cosmic Muons

Beam halo and cosmic muons are two sources of particles which are not produced in LHC collisions but can be found in the CMS detector nevertheless. Whereas beam halo muons move predominantly along the beam axis, cosmic muons typically traverse the detector from the top to the bottom. On the way through CMS the muons hit detector material. The space-time coordinates of these hits are analyzed and quantitative results are presented. This work is intended to build the basis for reconstruction, trigger, alignment, calibration and background studies with beam halo and cosmic muons.
