“…Further improvements to equation (33) have been proposed (see, e.g. [54,55]). Unlike the di-pion case the Coulomb correction for three equally charged pions at Q 3 = 0.25 GeV is not negligible and, as seen in figure 8, amounts to about 7%.…”

The application of the Bose-Einstein and Fermi-Dirac interferometry to multi-hadron final states of particle reactions is reviewed. The underlying theoretical concepts of particle interferometry is presented where a special emphasis is given to the recently proposed Fermi-Dirac correlation analysis. The experimental tools used for the interferometry analyses and the interpretation of their results are discussed in some details. In particular the interpretation of the dimension r, as measured from the interferometry analysis, is investigated and compared to that measured in heavy-ion collisions. Finally the similarity between the dependence of r on the hadron mass and the interatomic separation on the atomic mass in Bose condensates is outlined.

In previous works, in order to include correction by the Coulomb wave function in Bose-Einstein correlations (BEC), the two-body Coulomb scattering wave functions have been utilized in the formulation of three-body BEC. However, the threebody Coulomb scattering wave function, which satisfies approximately the three-body Coulomb scattering Schrödinger equation, cannot be written by the product of the two-body scattering wave functions. Therefore, we reformulate the three-body BEC, and reanalyze the data. A set of reasonable parameters is obtained. *

The recent data for Bose-Einstein Correlations (BEC) of three-charged particles obtained by NA44 Collaboration have been analysed using theoretical formula with Coulomb wave functions. It has been recently proposed by Alt et al. It turns out that there are discrepancies between these data and the respective theoretical values. To resolve this problem we seek a possibly modified theoretical formulation of this problem by introducing the degree of coherence for the exchange effect due to the BEC between two-identical bosons. As a result we obtain a modified formulation for the BEC of three-charged particles showing good agreement with the data. Moreover, we investigate physical connection between our modified formulation and the core-halo model proposed by Csörgő et al. Our study indicates that the interaction region estimated by the BEC of three-charged particles in the S + Pb collisions at 200 GeV/c per nucleon is equal to about 1.5 fm∼1.8 fm.
