Abstract

In a data sample of four million hadronic Z decays collected with the ALEPH detector at LEP, four Λ_b, baryon candidates are exclusively reconstructed in the Λ_b → 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 Λ_b, is measured to be 5614 ± 21 (stat.) ±4 (syst.) MeV/c².

N2 - 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.
