The existence of these states can be probed at the LHC in high energy proton-proton collisions. A novel search is presented for pair production of LQs coupled to a top quark and a muon using data at a center-of-mass energy of $13\\,\\mathrm{TeV}$, corresponding to an integrated luminosity of $35.9\\,\\mathrm{fb}^{-1}$, recorded by the CMS experiment. No deviation from the standard model prediction has been observed and scalar LQs decaying exclusively into $t\\mu$ are excluded up to masses of $1420\\,\\mathrm{GeV}$. The results of this search are combined with those from previous searches for LQ decays into $t\\tau$ and $b\\nu$, which excluded scalar LQs below masses of $900$ and $1080\\,\\mathrm{GeV}$. Vector LQs are excluded up to masses of $1190\\,\\mathrm{GeV}$ for all possible combinations of branching fractions to $t\\mu$, $t\\tau$ and $b\\nu$. With this analysis, all relevant couplings of LQs with an electric charge of $-1/3$ to third-generation quarks are probed for the first time.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.85765.v1/t1","@type":"Dataset","description":"Distributions for $M_{LQ}^{rec}$ (category A) after applying the full selection.
