Measurement of the Λb Polarization and Angular Parameters in Λb→J/ψΛ Decays from Pp Collisions at √s = 7 and 8 TeV
An analysis of the bottom baryon decay Λb→J/ψ(→μ+μ−)Λ(→pπ−) is performed to measure the Λb polarization and three angular parameters in data from pp collisions at √s=7 and 8 TeV, collected by the CMS experiment at the Large Hadron Collider. The Λb polarization is measured to be 0.00±0.06(stat)±0.06(...
