  The X17 particle, the E38 particle, and the anomalous soft photons are
anomalous particles because they do not appear to belong to any known Standard
Model families. We propose a QED meson description of the anomalous particles
as composite systems of a light quark and a light antiquark bound and confined
by the compact QED interaction, by combining Polyakov's transverse confinement
of opposite electric charges in compact QED in (2+1)D and Schwinger's
longitudinal confinement for massless opposite electric charges in QED in
(1+1)D. With predicted QED meson masses close to the observed X17 and E38
masses, QED mesons may be good candidates for the description of the anomalous
particles.
