Abstract
A search for B-s(0)-(B) over bar(s)(0) oscillations is performed in a sample of B-s(0) semileptonic decays collected using dilepton triggers at the Tevatron Collider during 1992-1995. The B-s(0) is reconstructed using phi mesonlepton correlations; its initial production flavor is determined with the second lepton in the event. From a signal of 1068 with a B-s(0) purity of 61%, we obtain a limit on the B-s(0)-(B) over bar(s)(0) oscillation frequency of Delta m(s) > 5.8 ps(-1) at 95% confidence level.
