Testing the Electron Tagging System of the KEDR Detector Using Muon Pairs Produced in Photon-Photon Collisions

摘要

The e(+)e(-) - e(+)e(-) + mu(+)mu(-) events selected in the central part of the KEDR detector are used for testing the energy calibration of the scattered electron tagging system and estimating the efficiencies for tagging one and two scattered electrons as a function of the virtual photon energy.
