NEUTRALINO MASS BOUNDS IN THE NEXT-TO-MINIMAL SUPERSYMMETRIC STANDARDMODEL

We analyze the experimental data from the search for new particles at LEP 100 and obtain mass bounds for the neutralinos of the Next-To-Mini mal Supersymmetric Standard Model (NMSSM). We find that for tan beta g reater-than-similar-to 5.5 a massless neutralino is still possible, wh ile the lower mass bound for the second lightest neutralino correspond s approximately to that for the lightest neutralino in the Minimal Sup ersymmetric Standard Model (MSSM).
