Abstract: (APS)

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