The measurements are performed using data corresponding to an integrated luminosity of 4.9 fb(-1), collected with the LHCb experiment. The polarisation is determined in a fiducial region of Lambda(0)(b) transverse momentum and pseudorapidity of 1 < p(T) < 20 GeV/c and 2 < eta < 5, respectively. The data are consistent with Lambda(0)(b) baryons being produced unpolarised in this region. The parity-violating asymmetry parameter of the Lambda -> p pi(-) decay is also determined from the data and its value is found to be consistent with a recent measurement by the BES III collaboration.", optnote="WOS:000543735000001", optnote="exported from refbase (https://references.ific.uv.es/refbase/show.php?record=4449), last updated on Wed, 15 Jul 2020 13:44:05 +0000", issn="1029-8479", doi="10.1007/JHEP06(2020)110", opturl="https://arxiv.org/abs/2004.10563", opturl="https://doi.org/10.1007/JHEP06(2020)110", language="English" }
