Perturbative unitarity of Higgs derivative interactions

Understand

We study the perturbative unitarity bound given by dimension six derivative interactions consisting of Higgs doublets.

• These operators emerge from kinetic terms of composite Higgs models or integrating out heavy particles that interact with Higgs doublets.
• They lead to new phenomena beyond the Standard Model.
• One of characteristic contributions by derivative interactions appear in vector boson scattering processes.
