Search for charge nonconservation and Pauli exclusion principle violation with the Majorana Demonstrator

MAJORANA Collaboration, I. J. Arnquist, F. T. Avignone +55

Charge conservation and the Pauli exclusion principle result from fundamental symmetries in the standard model of particle physics, and are typically taken as axiomatic. High-preci…
