SUMMARY:Structure of dimension-six derivative interactions in pseudo Nambu-Goldstone N Higgs doublet models\, Theory Seminar (High Energy/Cosmology)\, Yasuhiro Yamamoto\, University of Tokyo
DESCRIPTION:We derive the general structure of dimension-six derivative interactions in the N Higgs doublet models\, where Higgs fields arise as pseudo Nambu-Goldstone modes of a strongly interacting sector. We show that there are several relations among the dimension-six operators\, and therefore the number of independent operators decreases compared with models on which only SU(2)_L x U(1)_Y invariance is imposed. As an explicit example\, we derive scattering amplitudes of longitudinal gauge bosons and Higgs bosons at high energy on models involving two Higgs doublets\, and compare them with the amplitudes in the case of one Higgs doublet.
