Abstract

In a data sample of four million hadronic Z decays collected with the ALEPH detector at LEP, four Λb, baryon candidates are exclusively reconstructed in the Λb → Λ+cπ- channel, with the Λ+c decaying into pK-π+, pK-0 , or Λπ+π+π-. The probability of the observed signal to be due to a background fluctuation is estimated to be 4.2 × 10-4. The mass of the Λb, is measured to be 5614 ± 21 (stat.) ±4 (syst.) MeV/c2.
