Bose–Einstein and Fermi–Dirac interferometry in particle physics
The application of Bose–Einstein and Fermi–Dirac interferometry to multi-hadron final states of particle reactions is reviewed. The underlying theoretical concepts of particle interferometry are presented, where a special emphasis is given to the recently proposed Fermi–Dirac correlation analysis. The experimental tools used for interferometry analysis and the interpretation of the results obtained are discussed in detail. In particular, the interpretation of the dimension r, as measured from 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.
