## TL;DR

This paper introduces the Schwinger sum rule as a novel method to evaluate hadronic contributions to the muon g-2, with initial results on pseudoscalar mesons' light-by-light scattering effects.

## Contribution

It proposes using the Schwinger sum rule to analyze hadronic effects in muon g-2, offering a new approach for such calculations.

## Key findings

- Preliminary results for pseudoscalar meson contributions to muon g-2.
- Demonstration of the Schwinger sum rule's potential in hadronic physics.
- Initial insights into light-by-light scattering effects.

## Abstract

The Schwinger sum rule is presented as a new promising tool to study the hadronic contributions to the muon anomalous magnetic moment. In particular, we show preliminary results for the light-by-light scattering contribution of pseudoscalar mesons.
