The analysis is performed using an integrated luminosity of 138 fb$^{-1}$ of proton-proton (pp) collision data at a center-of-mass energy of 13 TeV produced by the LHC in 2016-2018. No significant excess over the predicted backgrounds is observed. Upper limits are set on the product of the inelastic dark matter production cross section $\\sigma$(pp $\\to$ A' $\\to$$\\chi_1$$\\chi_2$) and the decay branching fraction $\\mathcal{B}$($\\chi_2$$\\to$$\\chi_1 \\mu^+ \\mu^-$), where A' is a dark photon and $\\chi_1$ and $\\chi_2$ are states in the dark sector with near mass degeneracy. This is the first dedicated collider search for inelastic dark matter.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.140434.v1/t1","@type":"Dataset","description":"Definition of ABCD bins and yields in data, per match category.
