| Outline of Final Research Achievements |
We have studied possible new interactions beyond the standard model through top-quark productions/decays at hadron colliders. We first showed that we can achieve high precision in analyzing general top-gluon couplings by combining the data from Tevatron and LHC. We then derived the final-lepton momentum distribution, and thereby estimated the expected statistical uncertainties in measuring non-standard top-coupling parameters through the optimal-observable-analysis procedure. We moreover found that introducing a lepton-transverse-momentum cut is quite effective in order to avoid a constraint from the decoupling theorem. We also studied a possibility of detecting general top-Higgs couplings at a muon collider. We have published several papers on those results, which so far have been cited more than fifty times altogether.
