  2. 5. A Green's Basis for the Bosonic SMEFT to Dimension 8

    We present a basis of dimension-eight Green’s functions involving Standard Model (SM) bosonic fields, consisting of 86 new operators. Instead of using algebraic identities and integration by parts, we prove the independence of these interactions in momentum space, commenting about evanescent operators as well.
    In this talk, we show our method to construct a Green's Basis and our application...

  3. 20. Mapping the SMEFT to UV models for four-fermion operators

    The top-down matching of specific scenarios for new physics onto the Standard Model Effective Field Theory (SMEFT) is well-understood and easy to automise.
    The inverse approach, however, the bottom-up matching of the SMEFT to UV models and in particular a systematic exploration of these discoverable UV models is more difficult.
    I will present a diagrammatic technique for the automated...

    SmeftFR v3 [2302.01353, https://www.fuw.edu.pl/smeft/] enables derivation of Feynman rules for interaction vertices from the dimension-5, dimension-6 and (so far) all bosonic dimension-8 SMEFT operators which can be further easily used in numerical or symbolic calculations e.g. in Madgraph or FeynArts. There are many changes in comparison to the previous version of the code and its scope of...
