Neutralino decays in the minimal supersymmetric standard model
- Dipartimento di Fisica, Universita La Sapienza and Istituto Nazionale di Fisica Nucleare, Sezione di Roma, P.le Aldo Moro 2, I-00185 Rome (Italy)
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 {tilde {chi}}{sup 0}{sub 2}{r_arrow}{tilde {chi}}{sup 0}{sub 1}{gamma} and the decay into a light Higgs boson {tilde {chi}}{sup 0}{sub 2}{r_arrow}{tilde {chi}}{sup 0}{sub 1}{ital h}{sup 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. {copyright} {ital 1996 The American Physical Society.}
