Title: Search for the decays B{sup 0}{sub s}, B{sup 0}{sub d} {yields} e{+-}{mu}{-+} and Pati-Salam leptoquarks.

Abstract

We have searched for the decays B{sub s}{sup 0}{yields}e{sup {+-}}{mu}{sup {-+}} and B{sub d}{sup 0}{yields}e{sup {+-}}{mu}{sup {-+}} using a 102 pb{sup -1} data sample of p{ovr p} collisions at sqrt[s] = 1.8 TeV collected with the Collider Detector at Fermilab. We set upper limits on the branching fractions of B(B{sub s}{sup 0}{yields}e{sup {+-}}{mu}{sup {-+}})<6.1(8.2)x10{sup -6} and B(B{sub d}{sup 0}{yields}e{sup {+-}}{mu}{sup {-+}})<3.5(4.5)x10{sup -6} at 90(95)% confidence level. Using these limits, we set lower bounds on the corresponding Pati-Salam leptoquark masses and find that M{sub LQ}(B{sub s}{sup 0})>20.7(19.3) TeV/c{sup 2} and M{sub LQ}(B{sub d}{sup 0})>21.7(20.4) TeV/c{sup 2} at 90(95)% confidence level.
