QED Meson Description of the X17 and Other Anomalous Particles

TL;DR

This paper proposes a novel QED meson model to explain anomalous particles like X17 and E38, suggesting they are bound states of light quarks confined by compact QED interactions, with predicted masses aligning with observations.

Contribution

It introduces a new QED meson framework combining transverse and longitudinal confinement mechanisms to describe anomalous particles.

Findings

Predicted QED meson masses match observed X17 and E38 masses.

QED mesons are viable candidates for anomalous particle descriptions.

The model unifies confinement concepts in (2+1)D and (1+1)D QED.

Abstract

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.
