    "abstract": "We describe an experimental test of whether particle decay causes wave\nfunction collapse. The test uses interference between two well separated, but\ncoherent, sources of vector mesons. The short-lived mesons decay before their\nwave functions can overlap, so any interference must involve identical final\nstates. Unlike previous tests of nonlocality, the interference involves\ncontinuous variables, momentum and position. Interference can only occur if the\nwave function retains amplitudes for all possible decays. The interference can\nbe studied through the transverse momentum spectrum of the reconstructed\nmesons.",
