Study of Cosmics Data Tracks at Compact Muon Solenoid detector — •Natalie Heracleous and Adrian Perieanu — RWTH-Aachen, I. Physikalisches Institut Ib

An analysis of data taken in a Cosmic Run At Four Tesla (CRAFT) with the the Compact Muon Solenoid (CMS) detector at the Large Hadron Collider will be presented. In this study, cosmic muons and their track components are analyzed.

In CMS, the muon particle candidate can have an Inner and an Outer track component. The Inner track is reconstructed within the Tracker, while the Outer track in the Muon system. The Muon System provides muon identification and precise muon momentum resolution over a wide range. CRAFT data contain a large number of events with such reconstructed muons, O(10⁶). Issues related to matching of the two muon track components are studied.

Spectrum of transversal momentum and direction of high energetic muons are also presented.
