Unitarity bound in the composite two Higgs doublet model.
Presented by Ms. Emine YILDIRIM
Content
We discuss a composite two Higgs doublet model based on a symmetry breaking SO(6) × U (1)_x → SO(4) ×SO(2) × U (1)_x at a scale f, and explain how the effective kinetic terms and Yukawa interactions are obtained.
The coupling of the Higgs boson as a pseudo Nambu-Goldstone boson
to the standard model fields can deviate from
that of the standard model Higgs boson due to the non-linear feature.
These deviations cause
to unitarity violation at high energies because the cancellation of the quadratic energy terms does not happen.
We will examine the constrains on parameter space
from perturbative unitarity with a fixed energy scale in the composite two Higgs doublet model.
