Title: Light scalars with lepton number to solve the ( g 2 ) e anomaly

Journal Article · · Physical Review D

Scalars that carry lepton number can help mediate would-be lepton number–violating processes, such as neutrinoless double β decay or lepton scattering–mediated nucleon-antinucleon conversion. Here, we show that such new scalars can also solve the anomaly in precision determinations of the fine-structure constant α from atom interferometry and from the electron’s anomalous magnetic moment, ae ≡ (g – 2)e/2, by reducing |ae|. Study of the phenomenological constraints on these solutions favor a doubly charged scalar with mass below the GeV scale. Significant constraints arise from the measurement of the parity-violating asymmetry in Møller scattering, and we consider the implications of the next-generation MOLLER experiment at Jefferson Laboratory and of an improved ae measurement.
