2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/49218We simulate precision measurements of gauge-mediated supersymmetry breaking (GMSB) parameters at a 500 GeV e+e- linear collider in the scenario where a neutralino is the next-to-lightest supersymmetric particle. Information on the supersymmetry breaking and the messenger sectors of the theory is extracted from the measured sparticle mass spectrum and neutralino lifetime.LaTeX + sprocl.sty + epsf.sty, 6 pages, 3 figures (5 eps files)High Energy Physics - PhenomenologyHigh Energy Physics - Experimenttext
