Description

Duration: 15'+5'
Effective Field Theories (EFTs) provide a framework for capturing the effects of yet unseen heavy degrees of freedom in a model-independent manner. However, constructing a complete and minimal set of operators, especially at higher mass dimensions, is challenging.

In this talk, we present $\texttt{AutoEFT}$, an implementation of an algorithm that systematically handles redundancies among operators due to equations of motion, integration-by-parts identities, and repeated fields. This algorithm enables the construction of on-shell bases for a broad range of EFTs. Additionally, it facilitates the exploration of various aspects within this field, such as investigating higher mass dimensions or the relationship between different operator bases.

$\texttt{AutoEFT}$ can be applied to phenomenologically relevant theories like the Standard Model and its extensions, including new light particles or additional symmetry groups.
