Neutrino oscillations at JUNO, the Born rule, and Sorkin's triple path interference

Abstract:

We argue that neutrino oscillations at JUNO offer a unique opportunity to study Sorkin's triple path interference, which is pbkp_redicted to be zero in canonical quantum mechanics by virtue of the Born rule. In particular, we compute the expected bounds on triple path interference at JUNO and demonstrate that they are comparable to those already available from electromagnetic probes. Furthermore, the neutrino probe of the Born rule is much more direct due to an intrinsic independence from any boundary conditions, whereas such dependence on boundary conditions is always present in the case of electromagnetic probes. Thus, neutrino oscillations present an ideal probe of this aspect of the foundations of quantum mechanics.
