TL;DR
This paper investigates how extra dimensions and magnetic fluxes affect particle dipole moments, deriving constraints from experimental data on muon, neutron, and electron dipole moments to limit the size of extra dimensions and magnetic fluxes.
Contribution
It provides new bounds on the size of extra dimensions and magnetic fluxes based on precise measurements of particle dipole moments.
Findings
Constraints on the compactification size of extra dimensions.
Limits on magnetic flux threading the extra dimension.
Implications for theories with extra dimensions.
Abstract
The propagation of charged particles and gauge fields in a compact extra dimension contributes to of the charged particles. In addition, a magnetic flux threading this extra dimension generates an electric dipole moment for these particles. We present constraints on the compactification size and on the possible magnetic flux imposed by the comparison of data and theory of the magnetic moment of the muon and from limits on the electric dipole moments of the muon, neutron and electron.
