Mixing the Strong and E-W Higgs Sectors
After noting the well known similarity of the minimal electro-weak Higgs sector with the simple linear sigma model for the pion and σ I observe that a small mixing term between the two models generates a pion mass. Although both sectors, taken separately or together, have the same custodial SU(2)L×SU(2)R (and gauged SU(2)L×U(1) symmetry), the mixing breaks the relative chiral symmetry between t...

After noting the well known similarity of the minimal electro-weak Higgs sector with the linear sigma model for the pion and the sigma, it is found that a small mixing term between the two models generates a pion mass. Although the custodial SU(2)L × SU(2)R, and the gauged SU(2)L×U(1) symmetry for the whole model remains intact, the mixing breaks the relative chiral symmetry between the two sec...
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 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.
