Can the double-slit experiment distinguish between quantum interpretations?

Despite quantum mechanics' success, fundamental problems like the measurement problem and quantum arrival time problem cause ambiguities in its predictions. This paper shows that different interpretations of quantum theory yield varying predictions for the joint spatiotemporal distribution of particle detection events in a double-slit experiment. These differences, although usually small, can be experimentally distinguished using a proposed unconventional double-slit configuration realizable with current single-atom interferometry. This experiment would enhance our understanding of quantum mechanics' foundations.
