Search for resonant production of second-generation sleptons with same-sign dimuon events in proton–proton collisions at √s = 13 TeV

A search is presented for resonant production of second-generation sleptons (μL, νμ) via the R-parityviolating coupling λ 211 to quarks, in events with two samesign muons and at least two jets in the final state. The smuon (muon sneutrino) is expected to decay into a muon and a neutralino (chargi...
