5. MATCHETE - Automated One-Loop Matching with Function Methods

Matthias König

14/09/2022, 14:00

In this talk I will present an overview of the Mathematica software suite "MATCHETE". Starting from a Lagrangian provided by the user, MATCHETE determines the effective low-energy Lagrangian with matching conditions up to one-loop order using functional methods. I will discuss the matching procedure and highlight some of the technical challenges arising from operator reduction and evanescent operators.

6. Matching dictionaries at one loop

The complete matching between the SMEFT and any of its UV completions is known at tree level, and it has been collected in the form of a dictionary connecting BSM fields and their couplings to the corresponding low-energy effective interactions. The recent developments in matching codes will allow to extend this dictionary to one loop in the near future. The large amount of data generated in...

14. Consistent calculations at dim8 order

Janusz Rosiek

15/09/2022, 14:45

I will discuss how to perform consistent calculations at SMEFT including dim6, dim6^2 and dim8 corrections. Further I will present the automatic tools facilitating such calculations and directly expressing the results in terms of user-defined set of input quantities (usually observables taken from the experiment). I will illustrate the results with few chosen examples.
