Leptoquarks (LQ) with couplings to the third generation of Standard Model\n(SM) quarks have been proposed as possible explanations of the flavour\nanomalies indicating the violation of lepton flavour universality (LFV). The\nCMS collaboration has initiated an extensive search programme for these new\nstates in the LHC run-2 data recorded at \√(s)=13 TeV. In this article,\nthe CMS search results in the LQ pair-production final states \τ b ,\τ b,\n\ν t ,\ν t, \ν b ,\ν b, \τ t ,\τ t, and \μ t ,\μ t, as well\nas in the LQ single-production final state \τ ,\τ b are discussed. No\nsignificant deviation from the SM is observed in any of these channels. For a\nbroad range of LQ decay modes, exclusion limits on the LQ masses are determined\nat 95% confidence level reaching from 1.0 TeV to 1.8 TeV.\n
