Sensitive test for models of bose-einstein correlations
Accurate and sensitive measurements of higher order cumulants open up new approaches to pion interferometry. It is now possible to test whether a given theoretical prediction can match cumulants of both second and third order. Our consistency test utilizes a new sampling technique combining theoretically predicted functions with experimentally determined weights in a quasi-Monte Carlo approach. Testing a simplified version of a quantum statistics-based framework of Bose-Einstein correlations with this technique, we find that predictions for third order cumulants differ significantly from UA1 data. This discrepancy may point the way to more detailed dynamical information.
