Reconstruction of Basic Parameters from Chargino Production
S. Y. Choi, J. Kalinowski
The event characteristics of chargino pair production at e+e- collisions are explored to determine gaugino-higgsino mixing angles. We demonstrate that by measuring total cross sect…
Neutralino-Nucleus Elastic Scattering in the MSSM with Explicit CP Violation
S. Y. Choi
We re-investigate the neutralino-nucleus elastic scattering as a promising dark matter detection mechanism including contributions from the scalar-pseudoscalar mixing of neutral Hi…
CP Phases in Supersymmetric Tri-lepton Signals at the Tevatron
S. Y. Choi, M. Guchait, H. S. Song +1
We have analyzed the supersymmetric tri-lepton signals for sparticle searches at the Tevatron in the minimal supersymmetric standard model with general CP phases without generation…
Neutrino Oscillations and R-parity Violating Collider Signals
S. Y. Choi, Eung Jin Chun, Sin Kyu Kang +1
R-parity and L violation in the MSSM would be the origin of the neutrino oscillation observed in Super-Kamiokande. A distinctive feature of this framework is that it can be tested…
Single-photon events in e^+ e^- collisions
S. Y. Choi, J. S. Shim, H. S. Song +2
We provide a detailed investigation of single-photon production processes in collisions with missing momenta carried by neutrinos or neutralinos. The transition amplitudes…
