We search for new particles that decay into b{ovr b} and are produced with W bosons in p{ovr p} collisions at {radical}(s)=1.8 TeV . The search uses 109{plus_minus}7 pb{sup {minus}1} accumulated by the CDF experiment at Fermilab. We select events with an e{nu} or {mu}{nu} , and two jets, one of them 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 19pb (95{percent} C.L.) as the particle mass varies from 70 to 120 GeV/c{sup 2} . {copyright} {ital 1997} {ital The American Physical Society}
