Light Higgs bosons from a strongly interacting Higgs sector
The mass and the decay width of a Higgs boson in the minimal standard model are evaluated by a variational method in the limit of strong self-coupling interaction. The non-perturbative technique provides an interpolation scheme between strong-coupling regime and weak-coupling limit where the standard perturbative results are recovered. In the strong-coupling limit the physical mass and the deca...
متن کاملStrongly-interacting Heavy Flavors beyond the Standard Model A
The origin of mass must lie in physics beyond the Standard Model. Dynamical electroweak symmetry breaking models like technicolor can generate masses for the W and Z bosons. Providing the large top quark mass and large top-bottom mass splitting while keeping ∆ρ and flavor-changing neutral currents small requires new strong dynamics for the top and bottom quarks. In consequence, new particles ar...

متن کاملStrongly Interacting Higgs Sector without Technicolor
Simulation results are presented on Higgs mass calculations in the spontaneously broken phase of the Higgs sector in the minimal Standard Model with a higher derivative regulator. A heavy Higgs particle is found in the TeV mass range in the presence of a complex conjugate ghost pair at higher energies. The ghost pair evades easy experimental detection. As a nite and unitary theory in the contin...
متن کاملNew constraint on a strongly interacting Higgs sector.
We show that an integral S over the spectral function of spin-l states of the Higgs sector is constrained by precision weak-interaction measurements. Current data excludes large technicolor models; experiments at LEP and ‘SLC will sooi provide more stringent limits on Higgs strong interactions. Submitted to Physical Review Letters PACS numbers: 12.15.Cc, 12.15.Ji, 14.80.Er * Work supported by t...
