Bose-Einstein correlations for Lévy stable source distributions
نویسندگان
چکیده
The peak of the two-particle Bose-Einstein correlation functions has a very interesting structure. It is often believed to have a multivariate Gaussian form. We show here that for the class of stable distributions, characterized by the index of stability 0 < α ≤ 2, the peak has a stretched exponential shape. The Gaussian form corresponds then to the special case of α = 2. We give examples for the Bose-Einstein correlation functions for univariate as well as multivariate stable distributions, and check the model against two-particle correlation data.

Bose–Einstein correlations of pairs of identical charged pions produced in hadronic Z decays are analyzed in terms of various parametrizations. A good description is achieved using a Lévy stable distribution in conjunction with a model where a particle’s momentum is correlated with its space–time point of production, the τ -model. Using this description and the measured rapidity and transverse ...

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...

Bose-Einstein correlations and momentum distributions are calculated for a longitudinally expanding boson source, where the expanding system has a finite size in space-time rapidity. Such systems are physically realized in any of the single jets in high energy e + e − , lepton-hadron and hadron-hadron collisions as well as in high energy heavy ion collisions, where the projectile is not really ...
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...
