A non-linear representation of general scalar extensions of the Standard Model for HEFT matching

A non-linear representation of general scalar extensions of the Standard Model for HEFT matching

Abstract We introduce a non-linear representation of ultraviolet (UV) complete model, U representation, under which matching HEFT to general scalar extensions of the standard model is straightforward. The main idea is to express a scalar multiplet in its symmetric tensor representation rotated by U...
