Estimation of the material budget of the CMS Tracker using the triplet method

Silicon trackers are used extensively in high energy physics experiments. Estimation of the material budget of the tracker is crucial for the physics program of any experiment, especially for precision measurements, as it has a direct impact on reconstruction performance and calculation of systematic errors. In this paper, a novel method of estimating the material budget of the CMS Tracker using three consecutive hits from a reconstructed track is presented. Comparisons are made between the material budget obtained from data, and simulated events.
