A self-consistent calculation of non-spherical Bose-Einstein correlation functions with Coulomb final-state interaction

D\'aniel Kincses, M\'arton I. Nagy, M\'at\'e Csan\'ad

Bose-Einstein correlation functions with Coulomb effects can be calculated self-consistently for non-spherical sources.

The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We present a self-consistent generalization of the previous approach to non-spherical source functions and investigate the validity of the previously applied approximations assuming spherical symmetry. We present a software package that includes the calculation of a fully three-dimensional correlation function including the Coulomb interaction.

C2weakest assumption

The prior spherical-source method and its Coulomb treatment can be extended self-consistently to non-spherical sources without introducing uncontrolled errors or requiring new fitted parameters that undermine the generalization.

C3one line summary

The authors generalize their prior spherical-source method to non-spherical sources with a self-consistent treatment of Coulomb interactions and provide software for three-dimensional correlation functions.
