SUSY Particles

Oral

We report the resent development on the GRACE/SUSY system. GRACE/SUSY is the computer code which can generate Feynman diagrams in the MSSM automatically and compute 1-loop Feynman amplitudes in the numerical way. We present a short review of the GRACE/SUSY system. We also show new results of various 2-body decay widths and Chargino pair production at ILC in the 1-loop level.

SUSY Particles

Oral

Electroweak precision measurements can provide indirect information about the possible scale of supersymmetry already at the present level of accuracy. We perform a chi^2 fit in various SUSY scenarios including the W boson mass, the effective leptonic weak mixing angle, the anomalous magnetic moment of the muon, the decay b -> s gamma and the lightes MSSM Higgs boson mass, taking also into...

SUSY Particles

Oral

In many SUSY models the first SUSY signal in the proposed International Linear Collider is expected to come from the pair production of stau particles, followed by its decay into tau lepton plus lightest neutralino assumed to be the lightest supersymmetric particle. In our study a simple and robust method of measuring the polarization of this tau in its 1-prong hadronic decay...

SUSY Particles

Oral

In order to establish supersymmetry at future colliders, it is not sufficient to discover new particles, but the identity of gauge couplings and the corresponding Yukawa couplings between gauginos, sfermions and fermions needs to be verified. In detailed studies it was found that the SUSY-Yukawa couplings of the electroweak sector can be studied with great precision at the ILC, but a...
