dc.description.abstract | A measurement of the parity-violating decay asymmetry parameter, αb, and the helicity amplitudes for the decay Λ0b→J/ψ(μ+μ−)Λ0(pπ−) is reported. The analysis is based on 1400 Λ0b and Λ¯0b baryons selected in 4.6 fb−1 of proton–proton collision data with a center-of-mass energy of 7 TeV recorded by the ATLAS experiment at the LHC. By combining the Λ0b and Λ¯0b samples under the assumption of CP conservation, the value of αb is measured to be 0.30±0.16(stat)±0.06(syst). This measurement provides a test of theoretical models based on perturbative QCD or heavy-quark effective theory. | en_US |
