Phenomenology of $n$-$\bar{n}$ Oscillations Revisited

Abstract

We revisit the phenomenology of $n$-$\bar{n}$ oscillations in the presence of external magnetic fields, highlighting the role of spin. We show, contrary to long-held belief, that the $n$-$\bar{n}$ transition rate need not be suppressed, opening new opportunities for its empirical study.

arXiv comment15 pages, REVTeX; revised and rewritten to focus on SM spin-dependent effects, conclusions persist
