Effective Lagrangian Approach to Top Decay via Flavor Changing Neutral Current
Zenro Hioki, Kazumasa Ohkuma, Akira Uejima
We study possible non-standard and couplings, which induce flavor-changing neutral-current decays of the top quark, in the effective-Lagrangian framework. The correspon…
Correlations in flavor-changing tqZ couplings constrained via experimental data
Zenro Hioki, Kazumasa Ohkuma, Akira Uejima
Possible non-standard tqZ couplings, where q=c or u, originated from general flavor-changing-neutral-current interactions are studied model-independently using the effective Lagran…
Studying flavor-changing neutral tqZ couplings: Current constraints and future prospects
Zenro Hioki, Kazumasa Ohkuma, Akira Uejima
Possible non-standard tuZ and tcZ interactions, which induce flavor-changing neutral-current decays of the top quark, are studied in the effective-Lagrangian framework. The corresp…
Constraints on generalized non-standard couplings
Zenro Hioki, Kazumasa Ohkuma, Akira Uejima
General non-standard couplings are studied as model independently as possible based on the effective Lagrangian consisting of the dimension-6 operators, which is an extension…
Refined analysis and updated constraints on general non-standard tbW couplings
Zenro Hioki, Kazumasa Ohkuma, Akira Uejima
We recently studied possible non-standard tbW couplings based on the effective-Lagrangian which consists of four kinds of SU(3) x SU(2) x U(1) invariant dimension-6 effective opera…
Full analysis of general non-standard tbW couplings
Zenro Hioki, Kazumasa Ohkuma
Possible non-standard couplings which could contribute to the t -> b W process are studied based on the effective-Lagrangian approach. The corresponding effective Lagrangian consis…
