Description
Recent theory developments showed that the interplay between HEFT and SMEFT can be conveniently studied using differential geometry methods, where non-derivative field redefinitions are interpreted as coordinate changes on a 4D manifold. This approach is typically restricted to the study of the 2-derivative Lagrangian.
We introduce a possible strategy to extend the geometric interpretation to terms with 4 or more derivatives by employing the formalism of jet bundles, where field derivatives are treated as independent coordinates on a higher-dimensional manifold.
The talk will give a quick introduction to jet bundles and present preliminary results about the correspondence between metrics on jet bundles and the Lagrangian formulation of a toy EFT.
