Charged Particle Identification using the Liquid Xenon Calorimeter of the CMD-3 Detector

Vyacheslav Ivanov et al.


This paper describes a currently being developed procedure of the charged particle identification for CMD-3 detector, installed at the VEPP-2000 collider. The procedure is based on the application of the boosted decision trees classification method, and uses as input variables, among others, the specific energy losses of charged particle in the layers of the liquid Xenon calorimeter. The efficiency of the procedure is demonstrated by an example of the extraction of events of e+e- to K+K- process in the center of mass energy range from 1.8 to 2.0 GeV.
