Measurement of the parity-violating asymmetry parameter αb and the helicity amplitudes for the decay Λb0 →j /ψ Λ0 with the ATLAS detector
A measurement of the parity-violating decay asymmetry parameter, αb, and the helicity amplitudes for the decay Λb0→J/ψ(μ+μ-)Λ0(pπ-) is reported. The analysis is based on 1400 Λb0 and Λ¯b0 baryons selected in 4.6 fb-1 of proton-proton collision data with a center-of-mass energy of 7 TeV recorded by t...
