The work of SK has been funded by the European Union NextGenerationEU/PRTR under grant CNS2022-136024 and by MICIU/AEI/10.13039/501100011033 and FEDER/UE (grant PID2022-139466NB-C21). The work of SK is further supported by the Junta de Andalucía grant AST22_6.5. The next goalpost in precision calculations for physics beyond the Standard Model is determining the two-loop renormalization group (RG) equations in the Standard Model Effective Field Theory (SMEFT). We progress towards this goal by determining the RG equations for a simplified version of the SMEFT without any fermion fields. Our calculation relies on functional methods that are newly developed for multi-loop computations and adapted for the determination of RG equations here. 2025-06-27T11:05:28Z 2025-06-27T11:05:28Z 2025-05-14 journal article Born, L., Fuentes-Martín, J., Kvedaraite, S. et al.
