Measuring the top Yukawa coupling at the ILC at sqrt(s) = 500 GeV
Ryo Yonamine, Katsumasa Ikematsu, Tomohiko Tanabe +4
We report on the feasibility of the direct measurement of the top Yukawa coupling g_t at the International Linear Collider (ILC) during its first phase of operation with a center-o…
Bound-state Effects on Top Quark Production at Hadron Colliders
Kaoru Hagiwara, Yukinari Sumino, Hiroshi Yokoya
We study bound-state effects on the t\bar{t} production cross section in the threshold region at hadron colliders. The bound-state effects are important particularly at the LHC whe…
Single Longitudinal-Spin Asymmetries in Lepton-Pair Production at RHIC and J-PARC
Hiroshi Yokoya
We study the single longitudinal-spin asymmetries in lepton-pair production with large transverse-momentum at RHIC and J-PARC experiments. The asymmetries in the azimuthal angular…
Parity-Odd Asymmetries in W-Jet Events at the Tevatron
Kaoru Hagiwara, Ken-ichi Hikasa, Hiroshi Yokoya
Parity-odd asymmetries in the decay angular distribution of a W boson produced with a hard jet in p\bar{p} collisions arise only from QCD rescattering effects. If observed, these a…
Dilepton production near partonic threshold in transversely polarized proton-antiproton collisions
Hirotaka Shimizu, George Sterman, Werner Vogelsang +1
It has recently been suggested that collisions of transversely polarized protons and antiprotons at the GSI could be used to determine the nucleon's transversity densities from mea…
The Decay of Tau Leptons Produced in Neutrino-Nucleon Scatterings
Mayumi Aoki, Kaoru Hagiwara, Kentarou Mawatari +1
Energy and angular distributions of the tau decay products in the CERN-to-Gran Sasso appearance experiments are studied for the decay modes and (l=e o…
