Does particle decay cause wave function collapse: an experimental test

Klein, SR and Nystrand, Joakim LU (2003) In Physics Letters. Section A: General, Atomic and Solid State Physics 308(5-6). p.323-328
Abstract
We describe an experimental test of whether particle decay causes wave function collapse. The test uses interference between two well separated, but coherent, sources of vector mesons. The short-lived mesons decay before their wave functions can overlap, so any interference must involve identical final states. Unlike previous tests of non-locality, the interference involves continuous variables, momentum and position. Interference can only occur if the wave function retains amplitudes for all possible decays. The interference can be studied through the transverse momentum spectrum of the reconstructed mesons.
