Leptomeson contribution to the muon g-2

TL;DR

This paper proposes that leptomesons, hypothetical particles with lepton number and color, can explain the muon g-2 anomaly within current experimental constraints and are testable at the LHC.

Contribution

It introduces leptomesons as a new explanation for the muon g-2 discrepancy, expanding beyond traditional models.

Findings

Leptomesons can account for the muon g-2 anomaly within allowed mass and coupling ranges.

Leptomesons are testable at the current LHC run.

The model aligns with existing experimental constraints.

Abstract

Many models on the market allow for particles carrying both lepton number and color, e.g., leptoquarks and leptogluons. Some of the models with this feature can also accommodate color-singlet leptohadrons. We have found that the long-standing discrepancy between the experimental result and the Standard Model prediction for the muon anomalous magnetic moment can be explained by the effect of leptomesons within the wide allowed range of their masses and couplings. These new particles are testable at the current run of the LHC.
