# NLO corrections to the Delta F=2 Hamiltonian in the MSSM with non-degenerate squarks

## TL;DR

This paper calculates next-to-leading order QCD corrections to the Delta F=2 Hamiltonian in the MSSM, considering non-degenerate squark masses, enabling more precise studies of meson mixing.

## Contribution

It provides the first NLO corrections with exact squark mass diagonalization in the MSSM for neutral meson mixing analysis.

## Key findings

- NLO corrections improve theoretical precision.
- Results applicable to non-degenerate squark scenarios.
- Enhanced control over renormalization scheme dependence.

## Abstract

We present the next-to-leading strong interaction corrections to the Delta F=2 Hamiltonian in the MSSM with exact diagonalization of the squark mass matrices. These results allow phenomenological studies of neutral meson mixing in scenarios with non-degenerate squarks, with control over the renormalization scale and scheme dependence.
