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
-
This manuscript investigates one-loop corrections to stop annihilation, as well as non-perturbative Sommerfeld enhancement.
-
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.
