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