- Abstract
- We study the phenomenology of a supersymmetric scenario where the next-to-lightest superparticle is the lighter stau and is long-lived due to a very weakly coupled lightest superparticle, such as the gravitino. We investigate the LHC sensitivity and its dependence on the superparticle spectrum with an emphasis on strong production and decay. We do not assume any high-scale model for SUSY breaking but work along the lines of simplified models. Devising cuts that yield a large detection efficiency in the whole parameter space, we determine the LHC’s discovery and exclusion potential. This allows us to derive robust limits on \(m_{\tilde\tau_1}\), \(m_{\tilde g}\), a common \(m_{\tilde q}\), and \(m_{\tilde t_1}\). We briefly discuss the prospects for observing stopped staus.
