A Guide to Functional Methods Beyond One-Loop Order
Javier Fuentes-Martín, Adrián Moreno-Sánchez, Ajdin Palavrić +1
Functional methods can be applied to the quantum effective action to efficiently determine counterterms and matching conditions for effective field theories. We extend the toolbox…

Two-Loop Running in the Bosonic SMEFT Using Functional Methods
Lukas Born, Javier Fuentes-Martín, Sandra Kvedaraitė +1
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 F…

Functional Matching and Renormalization Group Equations at Two-Loop Order
Javier Fuentes-Martín, Ajdin Palavrić, Anders Eller Thomsen
We present a systematic method for determining the two-loop effective Lagrangian resulting from integrating out a set of heavy particles in an ultraviolet scalar theory. We prove t…
