We consider pair production of LSP staus at the LHC within R-parity violating supersymmetry. The staus decay into Standard Model leptons through the LL\=E operator. Using CheckMATE we have recast multileptonic searches to test such…

We consider scenarios in which the lightest sparticle (LSP) is the gravitino and the next-to-lightest sparticle (NLSP) is a metastable stau. We examine the production of stau pairs in e^{+}e^{-} annihilation at ILC and CLIC energies. In…

We investigate B3 mSUGRA models, where the lightest scalar tau, stau_1, is the LSP. B3 models allow for lepton number and R-parity violation; the LSP can thus decay. We assume one non-zero B3 coupling lambda'_ijk at M_GUT, which generates…
