Probing large extra dimensions with spin configuration of top quark pair production at the JLC
Kang Young Lee, JeongHyeon Song, Seong Chan Park +2
We explore signatures of large extra dimensions with a polarized electron/positrn beam at the Joint Linear Collider (JLC). We point out that spin informations can be useful to stud…
Measuring MSSM CP-violating Phases through Spin Correlated Supersymmetric Tri-lepton Signatures at the Tevatron
S. Y. Choi, M. Guchait, H. S. Song +1
We provide a detailed analysis of the supersymmetric tri-lepton signals for sparticle searches at the Tevatron in the minimal supersymmetric standard model with general CP-violatin…
Determining SUSY Parameters in Chargino Pair Production in e^+e^- Collisions
S. Y. Choi
In most supersymmetric theories, charginos belong to the class of the lightest supersymmetric particles and they are easy to observe at e^+e^- colliders. By mea…
W boson production at upgraded HERA
M. N. Dubinin, H. S. Song
Event characteristics of boson production at HERA collider are untrivial and sensitive to the production mechanisms. We analyse the distributions of the four particle final sta…
Analytic reduction of transition amplitudes in radiative electroweak processes
Seungwon Baek, J. S. Shim, H. S. Song +1
It is shown that the transition amplitudes of radiative electroweak processes like $e^-e^+ \to ν_e \olν_e \ga$, $\ga e^- \to ν_e \olν_e e^-$, and $ν_e e^- \to ν_e e^- \ga$ can be r…
