Measurement of the parity-violating asymmetry parameter α[subscript b] and the helicity amplitudes for the decay Λ[0 over b] → J/ψΛ[superscript 0] with the ATLAS detector
A measurement of the parity-violating decay asymmetry parameter, α[subscript b], and the helicity amplitudes for the decay Λ[0 over b] → J/ψ(μ[superscript +]μ[superscript −])Λ[superscript 0](pπ[superscript −]) is reported. The analysis is based on 1400 Λ[0 over b] and [bar over Λ][0 over b] baryons...
