First measurement of the B S meson mass

First measurement of the B S meson mass

In a sample of about 1.1 million hadronic Z decays recorded with the ALEPH detector during the 1990–1992 running of LEP, two unambiguous B S meson candidates were observed. From these events the mass of the B S meson has been measured to be 5.3686 ± 0.0056 (stat.) ± 0.0015 (syst.) GeV.
