The analyzed data set corresponds to an integrated luminosity of 138 fb$^{-1}$ of proton-proton collisions collected at $\\sqrt{s}$ = 13 TeV in 2016-2018 at the CERN LHC. This is the first search at the LHC for new particles with charges between $e/$3 and 0.9$e$, including an extension of previous results at a charge of 2$e/$3. Masses up to 640 GeV and charges as low as $e/$3 are excluded at 95% confidence level. These are the most stringent limits to date for the considered Drell-Yan-like production mode.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.146758.v2/t1","@type":"Dataset","description":"Signal yields for the charge scenarios considered in the analysis, as well as their associateds uncertainties.","name":"Event yields in 2016BCDEF signal"},{"@id":"https://doi.org/10.17182/hepdata.146758.v2/t2","@type":"Dataset","description":"Signal yields for the charge scenarios considered in the analysis, as well as their associateds uncertainties.","name":"Event yields in 2016GH signal"},{"@id":"https://doi.org/10.17182/hepdata.146758.v2/t3","@type":"Dataset","description":"Signal yields for the charge scenarios considered in the analysis, as well as their associateds uncertainties.","name":"Event yields in 2017BCDEF signal"},{"@id":"https://doi.org/10.17182/hepdata.146758.v2/t4","@type":"Dataset","description":"Signal yields for the charge scenarios considered in the analysis, as well as their associateds uncertainties.","name":"Event yields in 2018ABCD signal"},{"@id":"https://doi.org/10.17182/hepdata.146758.v2/t5","@type":"Dataset","description":"Distribution of $N_{\\text{hits}}^{\\text{low dE/dx}}$ in the SR and the CR for the early 2016 data set, as well as for...","name":"Event yields in 2016BCDEF data"},{"@id":"https://doi.org/10.17182/hepdata.146758.v2/t6","@type":"Dataset","description":"Distribution of $N_{\\text{hits}}^{\\text{low dE/dx}}$ in the SR and the CR for the late 2016 data set, as well as for...","name":"Event yields in 2016GH data"},{"@id":"https://doi.org/10.17182/hepdata.146758.v2/t7","@type":"Dataset","description":"Distribution of $N_{\\text{hits}}^{\\text{low dE/dx}}$ in the SR and the CR for the 2017 data set, as well as for an...","name":"Event yields in 2017BCDEF data"},{"@id":"https://doi.org/10.17182/hepdata.146758.v2/t8","@type":"Dataset","description":"Distribution of $N_{\\text{hits}}^{\\text{low dE/dx}}$ in the SR and the CR for the 2018 data set, as well as for an...","name":"Event yields in 2018ABCD data"},{"@id":"https://doi.org/10.17182/hepdata.146758.v2/t9","@type":"Dataset","description":"Exclusion region (hatched) at 95% CL in the FCP charge-mass plane for the considered signal.
