Bose Einstein correlations between charged and neutral pion pairs in OPAL at LEP
Abstract
With the OPAL detector at LEP we measured at the Z0 peak the Bose-Einstein correlations between charged pion pairs and between neutral pion pairs. We find that the emitting source of charged pion pairs is not spherical. The average radius of a spherical emitting region for neutral pion pairs seems to be smaller than that for charged pion pairs. The results are discussed.
