We have searched for the decays Bs0e±μ and Bd0e±μ using a 102pb-1 data sample of pp̅ collisions at s = 1.8TeV collected with the Collider Detector at Fermilab. We set upper limits on the branching fractions of B(Bs0e±μ)<6.1(8.2)×10-6 and B(Bd0e±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(Bs0)>20.7(19.3) TeV/c2 and MLQ(Bd0)>21.7(20.4) TeV/c2 at 90(95)% confidence level.
