TL;DR

This paper explores how the Kalb-Ramond antisymmetric tensor field can explain the muon g-2 anomaly by calculating its contribution and fitting experimental data without impacting electron measurements.

Contribution

It introduces the Kalb-Ramond tensor field as a novel solution to the muon g-2 problem and demonstrates its compatibility with existing electron g-2 results.

Findings

Kalb-Ramond tensor field can account for muon g-2 anomaly

The model fits experimental muon g-2 data by adjusting coupling

Electron g-2 results remain unaffected

Abstract

We investigate the Kalb-Ramond antisymmetric tensor field as solution to the muon $g-2$ problem. In particular we calculate the lowest-order Kalb-Ramond contribution to the muon anomalous magnetic moment and find that we can fit the new experimental value for the anomaly by adjusting the coupling without affecting the electron anomalous magnetic moment results.
