If the stop is the next-to-lightest supersymmetric particle (NLSP) and the mass difference to the neutralino is smaller than the top mass, it can decay via flavour-violating decay modes to cχ01/uχ01 or a four-body decay to bχ10ff', which above the W boson threshold corresponds to the decay to bχ10W. Improving on existing calculations for these decay modes, we analyse the branching ratios (BRs) for the respective decays and show that they can significantly deviate from one.
