The data correspond to an integrated luminosity of $138\\text{ fb}^{-1}$. Eight scenarios are considered, in which nonresonant scalar or vector LQs couple up or down quarks to electrons or muons, for dilepton invariant masses above $500$ GeV. LQ masses are probed up to $5$ TeV, heavier than those probed by previous pair-production and single-production searches. The differential distributions of dilepton events are fit to templates constructed from simulated standard model events that are reweighted to the form of the Drell-Yan cross section with LQ exchange. Limits are set on LQ-fermion coupling strengths for various LQ masses at $95\\%$ confidence level (CL). For scalar LQs with masses in the $1-5$ TeV range, coupling values greater than $0.3-1.0$ $(0.4-1.3)$ are excluded for LQs coupled to an electron/muon and an up (down) quark.  For vector LQs, coupling values greater than $0.1-0.5$ $(0.3-1.4)$ are excluded for LQs coupled to an electron/muon and an up (down) quark.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t1","@type":"Dataset","description":"The observed data in the dielectron channel and the fitted signal-plus-background templates, shown for the $S_{e u}$ scenario with a...","name":"Figure 3"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t2","@type":"Dataset","description":"Upper limits at $95\\%$ CL on the LQ-fermion couplings, $|y_{e u}|$, versus $S_{e u}$ mass for scalar LQs coupled to...","name":"Figure 11 (left)"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t3","@type":"Dataset","description":"The observed data in the dielectron channel and the fitted signal-plus-background templates, shown for the $S_{e d}$ scenario with a...","name":"Figure 4"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t4","@type":"Dataset","description":"Upper limits at $95\\%$ CL on the LQ-fermion couplings, $|y_{e d}|$, versus $S_{e d}$ mass for scalar LQs coupled to...","name":"Figure 11 (right)"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t5","@type":"Dataset","description":"The observed data in the dimuon channel and the fitted signal-plus-background templates, shown for the $S_{\\mu u}$ scenario with a...","name":"Figure 5"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t6","@type":"Dataset","description":"Upper limits at $95\\%$ CL on the LQ-fermion couplings, $|y_{\\mu u}|$, versus $S_{\\mu u}$ mass for scalar LQs coupled to...","name":"Figure 12 (left)"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t7","@type":"Dataset","description":"The observed data in the dimuon channel and the fitted signal-plus-background templates, shown for the $S_{\\mu d}$ scenario with a...","name":"Figure 6"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t8","@type":"Dataset","description":"Upper limits at $95\\%$ CL on the LQ-fermion couplings, $|y_{\\mu d}|$, versus $S_{\\mu d}$ mass for scalar LQs coupled to...","name":"Figure 12 (right)"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t9","@type":"Dataset","description":"The observed data in the dielectron channel and the fitted signal-plus-background templates, shown for the $V_{e u}$ scenario with a...","name":"Figure 7"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t10","@type":"Dataset","description":"Upper limits at $95\\%$ CL on the LQ-fermion couplings, $|g_{e u}|$, versus $V_{e u}$ mass for vector LQs coupled to...","name":"Figure 13 (left)"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t11","@type":"Dataset","description":"The observed data in the dielectron channel and the fitted signal-plus-background templates, shown for the $V_{e d}$ scenario with a...","name":"Figure 8"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t12","@type":"Dataset","description":"Upper limits at $95\\%$ CL on the LQ-fermion couplings, $|g_{e d}|$, versus $V_{e d}$ mass for vector LQs coupled to...","name":"Figure 13 (right)"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t13","@type":"Dataset","description":"The observed data in the dimuon channel and the fitted signal-plus-background templates, shown for the $V_{\\mu u}$ scenario with a...","name":"Figure 9"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t14","@type":"Dataset","description":"Upper limits at $95\\%$ CL on the LQ-fermion couplings, $|g_{\\mu u}|$, versus $V_{\\mu u}$ mass for vector LQs coupled to...","name":"Figure 14 (left)"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t15","@type":"Dataset","description":"The observed data in the dimuon channel and the fitted signal-plus-background templates, shown for the $V_{\\mu d}$ scenario with a...","name":"Figure 10"},{"@id":"https://doi.org/10.17182/hepdata.156848.v2/t16","@type":"Dataset","description":"Upper limits at $95\\%$ CL on the LQ-fermion couplings, $|g_{\\mu d}|$, versus $V_{\\mu d}$ mass for vector LQs coupled to...","name":"Figure 14 (right)"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins2904423?version=2"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/156848"}],"inLanguage":"en","name":"Search for $t$-channel scalar and vector leptoquark exchange in the high-mass dimuon and dielectron spectra in proton-proton collisions at $\\sqrt{s}$ = 13 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins2904423?version=2","version":2}
