Title: Search for B$$0\atop{s}$$ oscillations at D0

Abstract

Measurement of the B$$0\atop{s}$$ oscillation frequency via B$$0\atop{s}$$ mixing analyses provides a powerful constraint on the CKM matrix elements. A search for B$$0\atop{s}$$ oscillations was performed using data collected by the DØ detector during the period 2002-2005 at the Fermilab Tevatron. Approximately 610 pb -1 of data was analyzed to reconstruct a large set of B0 s mesons in different semileptonic decay modes. Opposite-side flavor tagging algorithms that were tested on semileptonic B0 d decays with the measurement of the B$$0\atop{d}$$ mixing frequency were used to determine the initial state flavor of the reconstructed B0 s meson. No significant signal for any particular value of the oscillation frequency was found. A 95% confidence level limit on the B$$0\atop{s}$$ oscillation frequency Δm s > 7.3 ps -1 and a sensitivity of 9.5 ps -1 were obtained.
