The search is performed in the same-sign dimuon final state using a proton-proton collision data set recorded at $\\sqrt{s}=13$ TeV, collected with the CMS detector and corresponding to a total integrated luminosity of 138 $\\text{fb}^{-1}$. The results are found to agree with the predictions of the standard model. For heavy Majorana neutrinos, constraints on the squared mixing element between the muon and the heavy neutrino are derived in the heavy neutrino mass range $50$ GeV -- $25$ TeV; for masses above 650\\GeV these are the most stringent constraints from searches at the LHC to date. A first test of the Weinberg operator at colliders provides an observed upper limit at 95\\% confidence level on the effective $\\mu\\mu$ Majorana neutrino mass is $10.8$ GeV.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.130825.v1/t1","@type":"Dataset","description":"Distribution of $H_T / p_{T}^{\\mu_{1}}$ for signals, backgrounds and data.
