Description
Compared with SMEFT, HEFT is applicable to a broader class of spontaneous symmetry breaking scenarios. However, its non-linear structure and the fact that HEFT is formulated directly in the broken phase make UV-HEFT matching more challenging. In the first part of this talk, we present a non-linear framework for ultraviolet theories that is particularly suitable for implementing UV-HEFT matching with functional methods. Building on this framework, we then show in the second part, through comparisons among different HEFT formulations, that primary HEFT (pHEFT) preserves maximal UV information and can serve as a precision benchmark for UV-HEFT matching. pHEFT therefore provides a universal matching scheme that is well suited for the automation of UV-HEFT matching.
