The analysis considers two effective field theory models with dimension-six operators; involving four-fermion contact interactions between two leptons ($\\Pell\\Pell$, electrons or muons) and $\\PQb$ or $\\PQs$ quarks (\\bbll and \\bsll). Two lepton flavor combinations ($\\Pe\\Pe$ and $\\PGm\\PGm$) are required and events are classified as having 0, 1, and $\\ge2$ b-tagged jets in the final state. No significant excess is observed over the standard model backgrounds. Upper limits are set on the product of production cross section of the new physics signals. These translate into lower limits on the energy scale $\\Lambda$ of 6.9 to 9.0\\TeV in the \\bbll model, depending on model parameters, and on the ratio of energy scale and coupling of the underlying physics, \\lamdagstar of 2.0 to 2.6\\TeV in the \\bsll model. The latter represent the most stringent limits on this model to date. Lepton flavor universality is also tested by comparing the dielectron and dimuon mass spectra for different $\\PQb$-tagged jet multiplicities. No significant deviation from the standard model expectation of unity is observed.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t1","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dimuon channel for different bbll signal scenarios","name":"bbll to dimuon 0b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t2","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dimuon channel for different bbll (destructive interference) signal scenarios","name":"bbll (destructive interference) to dimuon 0b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t3","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dimuon channel in 1b final state for different bbll signal scenarios","name":"bbll to dimuon 1b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t4","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dimuon channel in 1b final state for different bbll (destructive interference) signal scenarios","name":"bbll (destructive interference) to dimuon 1b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t5","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dimuon channel in 2b final state for different bbll signal scenarios","name":"bbll to dimuon 2b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t6","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dimuon channel in 2b final state for different bbll (destructive interference) signal scenarios","name":"bbll (destructive interference) to dimuon 2b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t7","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dielectron channel for different bbll signal scenarios","name":"bbll to dielectron 0b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t8","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dielectron channel for different bbll (destructive interference) signal scenarios","name":"bbll (destructive interference) to dielectron 0b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t9","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dielectron channel in 1b final state for different bbll signal scenarios","name":"bbll to dielectron 1b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t10","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dielectron channel in 1b final state for different bbll (destructive interference) signal scenarios","name":"bbll (destructive interference) to dielectron 1b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t11","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dielectron channel in 2b final state for different bbll signal scenarios","name":"bbll to dielectron 2b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t12","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dielectron channel in 2b final state for different bbll (destructive interference) signal scenarios","name":"bbll (destructive interference) to dielectron 2b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t13","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dimuon channel for bsll signal","name":"bsll to dimuon 0b and 1b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t14","@type":"Dataset","description":"Signal efficiencies with Full Run 2 dielectron channel for bsll signal","name":"bsll to dielectron 0b and 1b final state"},{"@id":"https://doi.org/10.17182/hepdata.156189.v1/t15","@type":"Dataset","description":"Observed and expected background yields for different mass ranges in the dielectron channel in 0 b jet final state.
