s events is used to eval- uate PID performance for kaons and pions from data. The average identification efficiencies and the misidenti- fication rates for pions (kaons) are 95% (90%) and 1% (3%) respectively. The typical separation between pi- ons and kaons varies from 8 standard deviations (σ) at momenta of 2 GeV/c to 2.5σ at 4 GeV/c. An electro- magnetic calorimeter (EMC) is used to identify electrons and photons. These systems are mounted inside a 1.5-T solenoidal magnet. The GEANT4 package [6] is used to simulate the response of the detector with varying ac- celerator and detector conditions. Event reconstruction efficiency is obtained using Monte Carlo (MC) simulated events having production characteristics from the JET- SET [7] fragmentation algorithm. Three-body D 0 decays are generated with uniform Dalitz plot [8] (phase space) distributions. Electromagnetic radiation from final state charged particles (FSR) is modeled using the PHOTOS package [9].
