Transverse Impact Parameter Resolution & Material Budget for CLIC and FCCee Peter Winkel Rasmussen July 25, 2017

Introduction The 2017-07-12 version of the ILC software was used. The CLIC o3 v11 and the FCCee o5 v03 detector models were used. Muons were fired with 1 GeV, 10 GeV and 100 GeV at various angles. This was repeated 2000 times. Events were reconstructed using truth tracking. σ ( d 0 ) for a given angle and energy was found by fitting a histogram of d 0 reco − d 0 truth with a Gaussian.
