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…
