Searches for R -parity-violating supersymmetry in pp collisions at s=8 TeV in final states with 0–4 leptons

V. Khachatryan, A. M. Sirunyan, A. Tumasyan, W. Adam et autres

Results are presented from searches for $R$-parity-violating supersymmetry in events produced in $pp$ collisions at $\sqrt{s}=8\text{ }\text{ }\mathrm{TeV}$ at the LHC. Final states with 0, 1, 2, or multiple leptons are considered independently. The analysis is performed on data collected by the …
