Abstract: We examine various scenarios that involve a light $$ \mathcal{O} $$ (1 TeV) leptoquark state and select those which are compatible with the current experimental values for ℬ(B s → μμ), $$ \mathrm{\mathcal{B}}{\left(B\to K\mu \mu \right)}_{\mathrm{large}-{q}^2},{R}_K={\mathrm{\mathcal{B}}}^{\prime}\left(B\to K\mu \mu \right)/{\mathrm{\mathcal{B}}}^{\prime}\left(B\to Kee\right) $$ , and which lead to predictions consistent with other experimental data. We show that two such scenarios are phenomenologically plausible, namely the one with a doublet of scalar leptoquarks of hypercharge 1/6, and the one with a triplet of vector leptoquarks of hypercharge 2/3. We also argue that a model with a singlet scalar leptoquark of hypercharge 1/3 is not viable. Using the present experimental data as constraints, it is shown that the exclusive lepton flavor violating decays, ℬ(B s → μτ), ℬ(B → Kμτ) and ℬ(B → K ∗ μτ), can be as large as $$ \mathcal{O}\left(1{0}^{-5}\right) $$ .
