Title: "Information on the Width Difference and Indirect CP Violation in the Bs System Using the Decay Bs to Ds()Ds()"

Abstract:

We present a study of the width difference between the heavy and light mass eigenstates, Delta Gamma_s = Gamma_L - Gamma_H, using the decays of Bs mesons to two Ds mesons. The results are based on a large data set of proton-antiproton collisions recorded by the Dzero detector operating at the Fermilab Tevatron Collider. Under certain assumptions, the branching fraction measurement can be related directly to Delta Gamma_s. It is interesting since one can measure Delta Gamma_s from branching ratios without information from lifetime fits.
