Spin Analysis of Supersymmetric Particles
S. Y. Choi, K. Hagiwara, H. -U. Martyn +2
The spin of supersymmetric particles can be determined at colliders unambiguously. This is demonstrated for a characteristic set of non-colored supersymmetric particles --…
Polarization in SUSY Cascade Decays
S. Y. Choi, K. Hagiwara, Y. G. Kim +2
leptons emitted in cascade decays of supersymmetric particles are polarized. The polarization may be exploited to determine spin and mixing properties of the neutralinos and st…
Solving the degeneracy of the lepton-flavor mixing angle theta_atm by the T2KK two detector neutrino oscillation experiment
Kaoru Hagiwara, Naotoshi Okamura
If the atmospheric neutrino oscillation amplitude, sin^2 2theta_atm is not maximal, there is a two fold ambiguity in the neutrino parameter space: sin^2 theta_atm>0.5 or sin^2 thet…
Improved predictions for g-2 of the muon and α_{\rm QED}(M_Z^2)
K. Hagiwara, A. D. Martin, Daisuke Nomura +1
We update the Standard Model predictions of the anomalous magnetic moment of the muon, a_μ= (g-2)/2, and the value of the QED coupling at the Z-boson mass, incorporating the new e^…
Physics potential of T2KK: An extension of the T2K neutrino oscillation experiment with a far detector in Korea
Kaoru Hagiwara, Naotoshi Okamura, Ken-ichi Senda
We study physics potential of placing a far detector in the east coast of Korea, where the off-axis beam from J-PARC at Tokai village for the T2K project has significant intensity…
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…
