摘要：

A complete phenomenological study of the next-to-lightest neutralino decays is performed in the MSSM. The widths and branching ratios for all the possible decay channels (including the radiative decay <(chi)over tilde(2)(0)>--><(chi)over tilde(1)(0)>gamma and the decay into a Light Higgs boson <(chi)over tilde(2)(0)> --> <(chi)over tilde(1)(0)h(0)>) are studied in detail as functions of all the SUSY parameters of the model. Particular attention is paid to situations that are interesting for searches at CERN LEP 2. Nontrivial decay patterns are found that critically depend on the region of the parameter space considered.
