Extended Higgs Sectors
I give a brief overview of the motivations for and experimental probes of extended Higgs sectors containing more than the single Higgs doublet field of the Standard
متن کاملBenchmarks for Higgs effective theory: extended Higgs sectors
Precise measurements of SM particles properties at the LHC allows to look for heavy New Physics in the context of an Effective Field Theory (EFT). These searches, however, often rely on kinematic regions where the validity of the EFT may be compromised. In this paper we propose to address this issue by comparing with benchmark models. The connection between models and their manifestations as EF...
متن کاملNonminimal Isotropic Cosmological Model with Yang-mills and Higgs Fields
We establish a nonminimal Einstein-Yang-Mills-Higgs model, which contains six coupling parameters. First three parameters relate to the nonminimal coupling of non-Abelian gauge field and gravity field, two parameters describe the so-called derivative nonminimal coupling of scalar multiplet with gravity field, and the sixth parameter introduces the standard coupling of scalar field with Ricci sc...
متن کاملProbing Exotic Higgs Sectors In`?`? Collisions
I review extended Higgs sectors and constraints thereon arising from ρ = 1, gauge-coupling unification and b → sγ. The couplings and decays of the Higgs boson eigen-states are outlined for triplet representations. Direct experimental probes of exotic Higgs bosons are reviewed with a focus on the important role that would be played by an e − e − or µ − µ − collider.
متن کاملCollider Signatures of Singlet Extended Higgs Sectors
We explore the collider signatures of the Higgs sectors in singlet-extended MSSM models. We find that even with reduced couplings due to singlet mixing, a significant portion of the parameter spaces have a discoverable Higgs via traditional decay modes or via invisible decays (directly to neutralinos or through cascade decays to neutralinos and neutrinos). For illustrative points in parameter s...
