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 BSmeson candidates were observed. From these events the mass of the BSmeson has been measured to be 5.3686 ± 0.0056 (stat.) ± 0.0015 (syst.) GeV.

Abstract
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 BSmeson candidates were observed. From these events the mass of the BSmeson has been measured to be 5.3686 ± 0.0056 (stat.) ± 0.0015 (syst.) GeV.I documenti in FLORE sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
