Scale dependence of top-quark cross section at colliders near production threshold at NNNLO
Yuichiro Kiyo
The top-quark threshold cross section at colliders near production threshold is investigated. We study the scale dependence of the cross section for ) ne…

Probing Scalar-Mediator Quark Couplings via CLFV Lepton-Nucleon Scattering
Yuichiro Kiyo, Michihisa Takeuchi, Yuichi Uesaka +1
We investigate charged lepton flavor violating (CLFV) deep-inelastic scattering, focusing on the gluon-initiated subprocess via the gluon effective operator…

Top Pair Production in e^+ e^- and gamma gamma Processes
Michihiro Hori, Yuichiro Kiyo, Jiro Kodaira +2
We analyze spin correlations between top quark and anti-top quark produced at polarized e^+ e^- and gamma gamma colliders. We consider a generic spin basis to find a strong spin co…
