Abstract
We study the effects of two-body Higgs boson scattering by exchanging unparticles. The unparticle contribution can change the standard model prediction for two-body Higgs boson scattering partial wave amplitude significantly leading to modification of the unitarity constraint on the standard model Higgs boson mass. For unparticle dimension dU between 1 and 2, the unitarity constraint on the Higgs boson mass can be larger than that in the standard model. Information on unparticle interaction can also be obtained. © 2008 The American Physical Society.
