Tagging sneutrino resonances at a linear collider with associated photons
Sneutrino resonances at a high-energy linear ${e}^{+}{e}^{\ensuremath{-}}$ collider may be one of the clearest signals of supersymmetry without $R$ parity, especially when the $R$-parity-violating coupling is too small to produce observable excesses in four-fermion processes. However, there is no guarantee that the sneutrino pole will lie anywhere near the machine …
