Fittino: general fit of MSSM parameters by using the
LC observables (e.g. cross-sections & masses). Some MSSM parameters are fitted with FITTINO (others fixed): Parameter Input Value Fit-Error without BR Fit-Error with BR (5.7%) tan b 9.0 6.29% 4.69% M1 99.54 0.092% 0.073% M2 192.57 0.140% 0.083%

● The smuon left decays into SPS1a scenario.
ISAJET 7.69 is used to generate the spectrum of masses, widths and BRs. Prefered mode: (~30.20%) . Other modes containing have high multiplicity final state (cascade decays from tau lepton). Charguino does decay substantially into staus. Assumption: universal BR right sleptons = 1 ( LSP candidate, m=95.5 GeV)
25
Slepton decays come from the coupling
Slepton prefers a Wino → cascade Slepton only decays to a Bino Charguino can decay into W and staus. have more complicate decays. Cascade decays could be observed if we have high efficiency. Up to 4 muons FS could be observed SUSY also give us important background
