SUPERSYMMETRY STUDIES AT FUTURE LINEAR E(-) COLLIDERS()E()

We examine various aspects of supersymmetric particle production at li near e(+)e(-) colliders operating at a center-of-mass energy of root s = 500 GeV, and integrated luminosity of integral Ldt = 20 - 50 fb(-1) . Working within the framework of the minimal supergravity model with gauge-coupling unification and radiative electroweak symmetry breaking (SUGRA), we study various signatures for detection of sparticles, tak ing into account their cascade decays, and map out the regions of para meter space where these are observable. We also examine strategies to isolate different SUSY processes from each other. In addition, we perf orm four detailed SUGRA case studies and examine the detectability of sparticles when several SUSY processes are occuring simultaneously. We show that precision mass measurements of neutralinos, sneutrinos, and top squarks are possible, in addition to previously studied precision mass measurements of sleptons and charginos.
