چکیده
|
We compute all of the one-loop corrections that are enhanced, o(λ i λ j /16π 2), in the limit s ≫ |λ i |v 2 ≫ m 2 , s ≫ m 12 2 to all the 2 → 2 longitudinal vector boson and higgs boson scattering amplitudes in the cp -conserving two-higgs doublet model with a softly broken $$ {mathrm{mathbb{z}}}_2 $$ symmetry. in the two simplified scenarios we study, the typical bound we find is |λ i (s)| ⪷ 4.
