Abstract

The paper describes a method of the charged particle identification, developed for the CMD-3 detector, installed at the VEPP-2000 e + e − collider. The method is based on application of boosted decision trees classifiers, trained for the optimal separation of electrons, muons , pions and kaons in the momentum range from 100 to 1200 MeV / c . The input variables for the classifiers are linear combinations of the energy depositions of charged particles in 12 layers of the liquid xenon calorimeter of the CMD-3. The event samples for training of the classifiers are taken from the simulation. Various issues of the calorimeter strip channels response simulation and their calibration are considered. Application of the method is illustrated by the examples of separation of the e + e − ( γ ) and π + π − ( γ ) final states and of selection of the K + K − final state at high energies.

Abstract

Since 2010 the CMD-3 detector has been collecting data at the e + e − collider VEPP-2000 at Budker Institute of Nuclear Physics. CMD-3 is a general purpose detector designed to study e + e − annihilation into hadrons in the wide energy range s = 0.3 – 2 GeV . The CMD-3 barrel electromagnetic calorimeter consists of two subsystems: closest to the beam pipe is the Liquid Xenon calorimeter and the outer one is based on CsI scintillation crystals. The design of the calorimeter and its current performance are presented.
