Title : A Bayesian statistical method for particle 
        identification in shower counters

Authors : N.Takashimizu, A.Kimura, A.shibata and T.Sasaki

Abstract : 
We report an attempt on identifying particles using a Bayesian
statistical method. We have developed the mathematical model and
software for this purpose. We tried to identify electrons and charged
pions in shower counters using this method. We designed an ideal shower
counter and studied the efficiency of identification using Monte Carlo
simulation based on Geant4. Without having any other information, e.g.
charges of particles which given by tracking detectors, we have achieved
95% purity of identification of both particles.
