This paper illustrates a method for the discrimination between πs and μs through the energy measurement and tracking capability of a hadron calorimeter followed by a system of chambers. Data taken in a test run with π and μ beams have been analyzed and compared with a sample indicated as π + μ. These π + μ events are obtained off line by taking one muon and one pion, superimposing their digital patterns and summing up their energy releases. The discriminant analysis employed provides a level of identification of about 99.5%. Such a result is very close to the physical limit corresponding to events with sail-through pions.

Abstract

This paper illustrates a method for the discrimination between πs and μs through the energy measurement and tracking capability of a hadron calorimeter followed by a system of chambers. Data taken in a test run with π and μ beams have been analyzed and compared with a sample indicated as π + μ. These π + μ events are obtained off line by taking one muon and one pion, superimposing their digital patterns and summing up their energy releases. The discriminant analysis employed provides a level of identification of about 99.5%. Such a result is very close to the physical limit corresponding to events with sail-through pions.
