Monopole charge quantization and the Aharonov–Bohm effect
Keyword(s):
We present a simple derivation of the Dirac monopole charge quantization condition, making explicit use of the Aharonov–Bohm effect. Since only the asymptotic field lines of the monopole play a crucial role, this derivation clearly shows that the quantization condition must hold unless the electrically charged particle and the monopole exchange new long-range forces. In particular, this implies that Cabrera's monopole event would be consistent with Fairbank's observations of free quarks only if the monopole carried long-range (unconfined) colour-magnetic fields.
