Description

Multi-boson processes are a valuable tool for deepening our understanding of the dynamics of the Higgs boson. In this talk we evaluate if they can be used to shed some light on the question of its transformation under the Standard Model symmetry group. To address this we resort to the application of on-shell amplitude methods to processes involving massive vectors and scalars. We construct the relevant kinematic structures for each case, match the results to both HEFT and SMEFT and analyze the differences between them in search of measurable phenomenological effects. The talk here presented is based on ongoing work that extends the results published in [2509.02680] for gluon fusion by my collaborators.
