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

TL;DR

This paper reevaluates neutron-antineutron oscillations considering spin effects and external magnetic fields, revealing that the transition rate may not be suppressed as previously thought, thus enabling new experimental approaches.

Contribution

It demonstrates that $n$-${ar n}$ oscillation rates are not necessarily suppressed by magnetic fields when spin is properly considered, challenging prior assumptions.

Findings

$n$-${ar n}$ transition rate may be unaffected by magnetic fields

Spin effects are crucial in understanding oscillation phenomenology

New experimental opportunities arise from this revised understanding

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.
