We examine various scenarios that involve a light (1 TeV) leptoquark state and select those which are compatible with the current experimental values for anot sign(B (s) -> mu mu), , 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, anot sign(B (s) -> mu tau), anot sign(B -> K mu tau) and anot sign(B -> K (au) mu tau), can be as large as O(10(-5)).
