CMS forward pixels geometry simulation

The large hadron collider (LHC) is being built at the European Center for Nuclear Research (CERN) to produce collisions between protons and protons at an unprecedented energy of 14 TeV. Compact muon solenoid (CMS) is one the five detectors that will be placed on the 17-mile-long ring of the LHC to record data for physics analysis from these collisions. The forward pixel detector of CMS is an integral part of the tracking system, which would play a key role in addressing the full physics potential of the collected data. This note describes the development of geometry simulation for the forward pixel detector.
