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 ...

Measurements of fiducial cross sections for the electroweak production of two jets in association with a Z-boson are presented. The measurements are performed using 20.3 fb−1 of proton-proton collision data collected at a ...
