Flavor-changing interactions with singlet quarks and their implications for the LHC

Katsuichi Higuchi, Katsuji Yamamoto

We investigate the flavor-changing interactions in an extension of the standard model with singlet quarks and singlet Higgs, which are induced by the mixing between the ordinary qu…

Universality of strength for Yukawa couplings with extra down-type quark singlets

Katsuichi Higuchi, Masato Senami, Katsuji Yamamoto

We investigate the quark masses and mixings by including vector-like down-type quark singlets in universality of strength for Yukawa couplings (USY). In contrast with the standard…
