Supersymmetric Scenarios with Dominant Radiative Neutralino Decay †

The radiative decay of the next-to-lightest neutralino into a lightest neutralino and a photon is analyzed in the minimal supersymmetric standard model. We find that significant regions of the supersymmetric parameter space with large radiative branching ratios (up to about 100%) do exist. The radiative channel turns out to be enhanced when the neutralino… CONTINUE READING
