Abstract
We calculate the full one-loop SUSY-QCD corrections to stop annihilation into gluons and light quarks including the Sommerfeld enhancement effect and discuss their impact on the neutralino relic density in the MSSM.

Strengths
1. This manuscript investigates one-loop corrections to stop annihilation, as well as non-perturbative Sommerfeld enhancement.
2. While the results show that the only important correction is from the Sommerfeld effect, such a careful calculation is very useful for QCD-related dark matter study.
Weaknesses
The results seem to be parameter-dependent, and some general quantitive conclusions would be desirable.
Report
The submission is well organized, providing both regularization details and the final corrections in a clear way. It thus meets the criteria of SciPost Physics Proceedings, and can be accepted.
