The International Linear Collider: Report to Snowmass 2021

Alexander Aryshev, Ties Behnke, Mikael Berggren +508

The International Linear Collider (ILC) is on the table now as a new global energy-frontier accelerator laboratory taking data in the 2030s. The ILC addresses key questions for our…

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…
