  1. 61. Functional Methods: How and When to Use Them
    Dr Anders Eller Thomsen (University of Bern)
    02/06/2025, 11:00

    Functional methods are a popular choice for various RG and EFT matching calculations, although many of the techniques have so far been limited to one-loop calculations. With the increasing demand for precision calculations, we have developed new, practical methods for the multi-loop level. In this talk, I will discuss these new techniques, contrast and compare them with ordinary diagrammatic...

  2. 20. Two-loop running in the SMEFT
    Lukas Born
    02/06/2025, 11:30

    The Standard Model Effective Field Theory (SMEFT) provides a powerful framework for parameterizing potential new physics in a model-independent way. In order to analyze data from experiments across different energy scales and extrapolate UV physics effects, it is crucial to know the renormalization group evolution (RGE) of SMEFT operators. In this talk, I will present the results for the...

  3. 18. Automating the computation of (generalized) functional supertraces beyond one loop
    Renato Fonseca (University of Granada)
    02/06/2025, 11:50

    There is growing interest in using functional methods for multi-loop calculations, such as effective field theory matching and the calculation of renormalization group equations. Beyond one loop, instead of evaluating functional traces, one must perform tensor contractions associated with certain graphs. In this talk I will discuss my ongoing work on FunGraphs, a package that aims to automate...

  4. 28. Two-loop renormalisation of quark and gluon fields in the SMEFT
    Giuseppe Ventura
    02/06/2025, 12:10

    We compute the contributions of CP-conserving operators in the dimension-six SMEFT to the two-loop renormalisation constants of quark and gluon fields. We work with the background-field method, which allows us to extract the contribution of these operators to the two-loop running of the top mass and the strong coupling constant. We discuss the mixing with the unphysical operators required for...
