Deviations from universality of slepton masses in the MSSM

TL;DR

This paper introduces a new ansatz for slepton mass matrices in the MSSM, allowing for exact diagonalization of a dominant sector, and investigates deviations from universality in slepton masses relevant for collider experiments.

Contribution

The paper proposes a novel ansatz for slepton mass matrices that enables exact diagonalization of a dominant sector, revealing potential deviations from universality in the MSSM.

Findings

Numerical analysis of slepton mass eigenstates shows deviations from universality.

The approach provides a new framework for studying slepton mass spectra.

Implications for slepton production at future colliders are discussed.

Abstract

In this paper we propose an ansatz that applies to the slepton mass matrices. In our approach these matrices contain a dominant sector that can be diagonalized exactly. We study the numerical results for the slepton mass eigenstates, looking for deviations from universality, which is usually assumed when one evaluates the production of sleptons at future colliders.
