3. Automatic generation of EFT operators

Renato Fonseca (University of Granada)

Effective field theories (EFTs) are a powerful tool for the exploration of potential new physics in a model-independent way. At a time when there is a lack of clarity on how to extend the Standard Model, the Standard Model effective field theory (SMEFT) and related EFTs have been receiving an increasing amount of attention. For example, the number of SMEFT operators, up to high mass...

4. CoDEx: Matching BSMs to SMEFT

Supratim Das Bakshi (Granada University)

14/09/2022, 11:45

I will present the Mathematica package - CoDEx that integrates out heavy fields of spin-0, 1/2, 1 and computes SMEFT effective operators up to mass dimension-6 and associated Wilson coefficients upto 1-loop-level in terms of the model parameters. The computation of Wilson coefficients is based on the evaluation of effective action formulae. I will discuss model implementation in CoDEx,...

17. Gamma5 in Dimensional Regularization: The BMHV scheme at two loop

Paul Kühler

We investigate the application of the BMHV scheme for treating Gamma5 in Dimensional Regularization. Looking at a toy example of a chiral QED, we observe that the BRST symmetry is broken in the presence of a non-anticommuting Gamma5. The symmetry breaking can be repaired by finite symmetry restoring counter terms which can be systematically calculated from insertions of evanescent operators....

12. RG Equation for Chiral Theories in DimReg & BMHV scheme: Application to Chiral-QED at 2 loops

Hermès Bélusca-Maïto

15/09/2022, 11:45

I discuss how renormalization group equations can be consistently established for chiral theories in the BMHV dimensional renormalization scheme, where the BRST symmetry has been restored with finite counterterms, by using notions from Algebraic Renormalization.

19. HEPfit: a code for the combination of indirect and direct constraints on high energy physics models

Jorge de Blas (Universidad de Granada)

16/09/2022, 11:00

𝙷𝙴𝙿𝚏𝚒𝚝 is a flexible open-source tool which, given the Standard Model or any of its extensions, allows to i) fit the model parameters to a given set of experimental observables; ii) obtain predictions for observables. 𝙷𝙴𝙿𝚏𝚒𝚝 can be used either in Monte Carlo mode, to perform a Bayesian Markov Chain Monte Carlo analysis of a given model, or as a library, to obtain predictions of observables for...

20. EOS

Meril Reboud

I present EOS, an open-source software dedicated to a variety of tasks in the processing of flavor physics observables. EOS is written in C++ and offers both a C++ and a Python interface. It is developed for three main tasks, the production of theoretical predictions for flavor physics observables; the inference of theoretical parameters from an extensible database of likelihoods; and the...
