Light Stop Decays [PDF]

arXiv, 2015
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 $c\tilde{\chi}^0_1/u\tilde{\chi}^0_1$ or a four-body decay to $b\tilde{\chi}_1^0f\bar{f}'$, which above the $W$ boson threshold corresponds to the decay to $b\tilde{\
