# Explanation of electron and muon g-2 anomalies in the MSSM

## TL;DR

This paper demonstrates that the electron and muon g-2 anomalies can be simultaneously explained within the MSSM by tuning superpartner contributions, involving light selectrons and charginos that evade current collider constraints.

## Contribution

It shows a viable MSSM parameter space where both anomalies are explained without large flavor violation, using specific superpartner mass arrangements.

## Key findings

- MSSM can account for both electron and muon g-2 deviations.
- Light selectrons and wino-like charginos are key to the explanation.
- Model evades current LHC constraints due to degenerate spectra.

## Abstract

The current experimental values of anomalous magnetic moments of muon and electron deviate from the Standard Model predictions by few standard deviations, which might be a hint of new physics. The sizes and signs of these deviations are different and opposite between the electron and muon, which makes it difficult to explain both of these anomalies in a consistent model without introducing large flavour-violating effects. It is shown that they can be simultaneously explained in the Minimal Supersymmetric Standard Model (MSSM) by arranging the sizes of bino-slepton and chargino-sneutrino contributions differently between the electron and muon sectors. The MSSM spectrum features very light selectrons and wino-like chargino, while they can evade LHC constraints due to degenerate spectra.
