abstract = "We have searched for the decays B0 s → e±μ∓ and B0 d → e±μ∓ using a 102pb-1 data sample of pp¯ collisions at √s = 1.8 TeV collected with the Collider Detector at Fermilab. We set upper limits on the branching fractions of B(B0 s → e±μ∓) < 6.1(8.2) × 10-6 and B(B0 d → e±μ∓) < 3.5(4.5) × 10-6 at 90(95)% confidence level. Using these limits, we set lower bounds on the corresponding Pati-Salam leptoquark masses and find that MLQ(B0 s) > 20.7(19.3) TeV/c2 and MLQ(B0 d) > 21.7(20.4) TeV /c2 at 90(95)% confidence level.",
