We search for new particles that decay into b{ovr b} and are produced with W bosons in p{ovr p} collisions at sqrt[s] = 1.8 TeV. The search uses 109 {+-} 7 pb{sup -1} accumulated by the CDF experiment at Fermilab. We select events with an e{nu} or {mu}{nu}, and two jets, one of the b tagged. The number of events and the two-jet mass distribution are consistent with expectations. Using W+Higgs production as a model for the acceptance, we set an upper limit on the production cross section times branching ratio for the new particle ranging from 14 to 19 pb (95% C.L.) as the particle mass varies from 70 to 120 GeV/c{sup 2}.
