Description:
Author(s): Thomas Gutsche, Mikhail A. Ivanov, Jürgen G. Körner, Valery E. Lyubovitskij, and Pietro Santorelli Recently the ATLAS Collaboration at CERN reported on the measurement of the branching ratio R Λ b = Γ ( Λ b 0 → ψ ( 2 S ) Λ 0 ) / Γ ( Λ b 0 → J / ψ Λ 0 ) . The measured branching ratio R Λ b = 0.501 ± 0.033 ( stat ) ± 0.019 ( syst ) was found to be lower than the covariant quark model prediction of R Λ b = 0.8 ± 0.1 calculated by us recently. We pre… [Phys. Rev. D 92, 114008] Published Tue Dec 01, 2015
