Correlations in flavor-changing tqZ couplings constrained via experimental data

Zenrō Hioki, Kazumasa Ohkuma, Akinori 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 Lagrangian consisting of several S U ( 3 ) × S U ( 2 ) × U ( …

Effective Lagrangian Approach to Top Decay via Flavor Changing Neutral Current

Kazumasa Ohkuma, Zenrō Hioki, Akira Uejima

We study possible non-standard $tuZ$ and $tcZ$ couplings, which induce flavor-changing neutral-current decays of the top quark, in the effective-Lagrangian framework. The corresponding interaction Lagrangian comes from several $SU(3) \times SU(2) \times U(1)$ invariant dimension-6 effective operators, and it includes four independent …

Studying flavor-changing neutral tqZ couplings: Current constraints and future prospects

Zenrō Hioki, Kazumasa Ohkuma, Akira Uejima

Possible nonstandard tuZ and tcZ interactions, which induce flavor-changing neutral-current decays of the top quark, are studied in the effective-Lagrangian framework. The corresponding Lagrangian consists of four kinds of nonstandard couplings coming from [Formula: see text] invariant dimension-6 effective operators. The four …

Constraints on generalized nonstandard $tbW$ couplings

Kazumasa Ohkuma, Zenrō Hioki, Akira Uejima

General non-standard $tbW$ couplings are studied as model independently as possible based on the effective Lagrangian consisting of the dimension-6 operators, which is an extension of the standard-model Lagrangian. The $tbW$-interaction Lagrangian in this framework includes four kinds of couplings, which could …
