Search for high-mass resonances decaying to dielectron or dimuon final states in proton-proton collisions at a center-of-mass energy of 8 TeV with 20.3 fb-1 in the dimuon channel and 20.5 fb-1 in the dielectron channel, collected in 2012. The final states used are 2 electrons or 2 muons.\n\nAll events meet the following requirements:\n\n- At least one reconstructed primary vertex with at least associated 3 tracks having pT > 0.4 GeV.\n- For data, events occurred during periods of stable beam with all relevant detector sub-systems operational.\n\nEvents are triggered by one of the following trigger selections:\n- A trigger requiring the presence of at least 2 energy deposits in the electromagnetic calorimeter, one with pT > 35 GeV, and the other with pT > 25 GeV. The shower profiles are required to be consistent with those expected for electromagnetic shower.\n- A trigger requiring the presence of at least one isolated muon with pT > 24 GeV or at least one muon with pT > 36 GeV.\n\nThe 2 electron channel is defined as:\n- 2 electrons with ET > 30 GeV.\n- 1 \"leading\" electron with ET > 40 GeV.\n- Electrons are in pseudorapidity range < 2.5.\n- Electrons in pseudorapidity range [1.37,1.52] are excluded.\n- Electron track and cluster satisfy criteria requiring shower profiles consistent with those expected.\n- Minimum requirement on the amount of transition radiation for electron tracks.\n- At least one hit in the first layer of the pixel detector required if an active pixel layer is traversed.\n- Electrons are isolated within a cone of radius DeltaR = 0.2 in the (eta,phi) plane: for leading electron energy in the cone < 0.007 * ET + 5.0 GeV, for subleading electron < 0.022 * ET + 6.0 GeV.\n\nThe 2 muon channel is defined as:\n- 2 oppositely-charged muons with pT > 25 GeV, each with a track component in both the Muon Spectrometer and the Inner Detector.\n- Each muon has a minimum number of hits in each ID component.\n- Impact parameter along the beam axis is < 1 mm, and transverse impact parameter is < 0.2 mm.\n- At least one muon in the pair passes a \"tight\" selection consisting of:\n>=1 hit in both trigger chamber layers;\n>=3 hits in each of three stations of the MS, or, for muons in the very forward region, >=2 hits in the CSC and >=3 hits in the middle and outer MS stations;\nDifference between ID and MS track momentum measurements is < 5 sigma.\n- One muon in the pair is allowed to pass a modified selection, consisting of:\nMuon is within pseudorapidity range < 1.05;\n>=5 precision hits in each of the inner and outer stations of the MS;\n>=1 hit in one trigger chamber layer;\nDifference between ID and MS track momentum measurements is < 5 sigma.\n\nIn all cases, the pair candidate with the highest sum pT is selected.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.65388.v1/t1","@type":"Dataset","description":"Z' Product of acceptance and efficiency for the dielectron and dimuon selections as a function of the SSM Z' pole...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.65388.v1/t2","@type":"Dataset","description":"Observed and predicted dielectron invariant mass (m_ee) distribution in the search region.
