Abstract

A four-dimensional method to unfold NA38 experimental distributions is presented. It is based on the Bayes theorem and uses an iterative procedure. Tests of this method on Monte-Carlo simulated distributions are described. Subtraction of the background is discussed. This method is applied to the S-U data collected in 1992 by the NA38 experiment.
