- Descripción
- The production of B∗ mesons in Z decays has been measured at LEP with the L3 detector. A sample of Z → b events was obtained by tagging muons in 1.6 million hadronic Z decays collected in 1991, 1992 and 1993. A signal with a peak value of Eγ = 46.3 ± 1.9 (stat) MeV in the B rest frame energy spectrum was interpreted to come from the decay B∗ → γB. The inclusive production ratio of B∗ mesons relative to B mesons was determined from a fit to the spectrum to be , where the first error is statistical and the second is systematic.
