BOSE-EINSTEIN CORRELATIONS IN PION PRODUCTION AT TRISTAN
Measurement of Bose-Einstein correlations in the production of like-signed pion pairs has been made with the AMY detector at TRISTAN. An event sample of 10120 hadronic events with ranging between 50 to 61 GeV was used. These measurements indicate a strength of the enhancement of ? = 0.61M.07, with a typical correlation size of Ro = 1.16±.08 fm. This value of ? is consistent with measurem...
متن کاملStable Bose-Einstein correlations
The shape of Bose-Einstein (or HBT) correlation functions is determined for the case when particles are emitted from a stable source, obtained after convolutions of large number of elementary random processes. The two-particle correlation function is shown to have a stretched exponential shape, characterized by the Lévy index of stability 0 < α ≤ 2 and the scale parameter R. The normal, Gaussia...
متن کاملIntermittency and Bose-Einstein correlations
The role of Bose-Einstein correlations in a widely discussed intermittency phenomenon is reviewed. In particular, it is shown that particle correlations of different origin are better displayed when analysed as functions of appropriately chosen variables. Correspondingly, if the shape of Bose-Einstein contribution is chosen to be Gaussian in 3momentum transferred, it provides the power-like law...
متن کاملBose-Einstein Correlations and Sonoluminescence
Sonoluminescence may be studied in detail by intensity correlations among the emitted photons. As an example, we discuss an experiment to measure the size of the light-emitting region by the Hanbury Brown-Twiss effect. We show that single bubble sonoluminescence is almost ideally suited for study by this method and that plausible values for the physical parameters are within easy experimental r...
متن کاملBose - Einstein Correlations of Pion
A wavepacket model for a system of free pi-ons, which takes into account the full permutation symmetry of the wavefunction and which is suitable for any phase space parametrization is developed. The properties of the resulting mixed ensembles and the two-particle correlation function are discussed. A physical interpretation of the chaoticity as localization of the pions in the source is present...
