Bounds for Bose-Einstein correlation functions.
Bounds for the correlation functions of identical bosons are discussed for the general case of a Gaussian density matrix. In particular, for a purely chaotic system the two-particle correlation function must always be greater than one. On the other hand, in the presence of a coherent component the correlation function may take values below unity. The experimental situation is briefly discussed....
متن کاملTesting the Core-Halo Model on Bose-Einstein Correlation Functions
Having first performed a Monte Carlo simulation to justify the analysis technique to be used, we then analyze the Bose-Einstein correlation functions from CERN experiment NA44 in the context of the core-halo model. Although experimental resolution and error bar distribution prevents a direct observation of the halo structure, the values for the core radius and the core fraction of pions can be ...
متن کاملShortest movie: Bose-Einstein Correlation functions in e+e− annihilations
Bose-Einstein correlations of identical charged-pion pairs produced in hadronic Z decays are analyzed in terms of various parametrizations. A good description is achieved using Lévy stable distributions. The source function is reconstructed with the help of the τ-model.
متن کاملOn the m⊥-dependence of Bose-Einstein correlation radii
Within a theoretical study using both HYLANDER and RQMD, we revisit Bose-Einstein correlation measurements of 200AGeV S+S and 160AGeV Pb+Pb. Transverse flow does not show up in the Bose-Einstein measurements. The decrease of the effective transverse radius parameters with increasing transverse average momentum of the particle pair is largely due to the effect of resonance decays. E. Mail: schle...
متن کاملNew Bose-einstein Results from L3
In hadronic Z decays, we compare Bose-Einstein correlations in π 0 pairs with those in identical charged pion pairs. We also measure Bose-Einstein correlations in triplets of identical charged pions. From the first study, the source radius is found to be smaller for π 0-π 0 than for π ±-π ± , as would be expected, e.g., in a string model. However, the second study shows that the data are consis...
