Neutralino Decays in the Minimal Supersymmetric Standard Model

  title={Neutralino Decays in the Minimal Supersymmetric Standard Model},
  author={S.Ambrosanio and B.Mele},
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 X0(2) -->X0(1) gamma and the decay into a light Higgs X0(2) -->X0(1) h0) are studied in detail as functions of all the SuSy parameters of the model. Particular attention is paid to situations that are interesting for LEP2 searches. Non-trivial decay patterns are found that critically depend on the… Expand
