| + | The relevant UFO file already exists here: https://arxiv.org/abs/1412.5589. One can independently vary the stop and neutralino mass splitting, as well as the coupling that enables decays, which are denoted gL and gR. For now we may as well set gL=gR, such that we have only three parameters: m_stop, m_chi, and g. For any value of the former two, we may choose a lifetime from the latter. | ||

| + | How does this model map onto the various searches (displaced jets, R-hadron etc)? Are there any blind spots? Are the searches effectively recastable? | ||
