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...

| description | 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 (chargino), which will then decay into a second muon
and at least two jets. The analysis is based on the 2016 data set
of proton-proton collisions at √s = 13 TeV recorded with
the CMS detector at the LHC, corresponding to an integrated
luminosity of 35.9 fb−1. No significant deviation is observed
with respect to standard model expectations. Upper limits on
cross sections, ranging from 0.24 to 730 fb, are derived in
the context of two simplified models representing the dominant signal contributions leading to a same-sign muon pair.
The cross section limits are translated into coupling limits
for a modified constrained minimal supersymmetric model
with λ
211 as the only nonzero R-parity violating coupling.
The results significantly extend restrictions of the parameter
space compared with previous searches for similar models |
