What Will LC Tell Us on Top/QCD ?

Zenro Hioki

Current status of Top/QCD studies at linear colliders (LC) is briefly viewed, classifying topics into two categories: those within the standard model and those beyond the standard…

New-Physics Search in gamma gamma --> t tbar

Zenro Hioki

We performed an analysis on possible anomalous top-quark couplings generated by SU(2) x U(1) gauge-invariant dimension-6 effective operators, applying the optimal-observable proced…

A New Decoupling Theorem in Top-Quark Physics

Zenro Hioki

Angular distribution of a secondary particle in top-quark production/decay is studied in a simple and general manner. It is shown that the distribution does not depend on any possi…

Kinematical Reconstruction of the ttbar System Near its Threshold at Future e+e- Linear Colliders

Katsumasa Ikematsu, Keisuke Fujii, Zenro Hioki +2

We developed a new method for full kinematical reconstruction of the ttbar system near its threshold at future linear e+e- colliders. In the core of the method lies likelihood fitt…

Probing Anomalous Top-Couplings through the Final Lepton Angular and Energy Distributions at Polarized NLC

Zenro Hioki

The angular and energy distributions of the final lepton in e ebar t tbar --> l^{+-} X at next linear colliders (NLC) are analyzed a model-independent way for arbitrary longitudina…

Probing Anomalous Top-Couplings at Polarized Linear Collider

Zenro Hioki

The energy spectra of the lepton(s) in eebar --> ttbar --> l^{+-}X/ l^+l^- X' at next linear colliders (NLC) are analyzed a model-independent way for arbitrary longitudinal beam po…
