| Abstract | This paper presents new measurements in a case study of the minimal SUGRA model with mo = 100 Ge V, m 1; 2 = 300 Ge V, Ao = 0, tan j3 = 2, and sgn 11 = + based on four-body distributions from three-step decays and on minimum masses in such decays. These measurements allow masses of supersymmetric particles to be determined without relying on a model. The feasibility of testing slepton universality at the ""' 0.1% level at high luminosity is discussed. In addition, the effect of enlarging the parameter space of the minimal SUGRA model is discussed. The direct production of left handed sleptons and the non-observation of additional structure in the dilepton invariant mass distributions is ~hown to provide additional constraints.
