Separation of e⁺e^- → e⁺e^- and e⁺e^- → π⁺π^- events using SND detector calorimeter

The technique of discrimination of the e⁺e^- e⁺e^- and e⁺e^- → π⁺π^- events in energy range 0.5 < √s < 1 GeV by energy deposition in the calorimeter of SND detector was developed by applying machine learning method. Identification efficiency for e⁺e^- → e⁺e^- and e⁺e^- → π⁺π^- events in the range from 99.3 to 99.8% has been achived.
