Simulation of High Energy Muons

Under the scope of a CERN summer student project, a Geant4 physical model has been developed and committed to the Geant4 repository to allow precise simulation of high-energy muons and hadrons transport inside a material. Resulted angular distributions produced by this model have small deviations from those that were obtained by the Geant4 model used by default. High-energetic muons energy losses inside the CMS tracker have also been estimated and may vary from 0.05% up to 2.5%.
