Abstract |
A measurement of the transverse polarization of the Lambda and (Lambda) over bar hyperons in pNe fixed-target collisions at root s(NN) = 68.4 GeV is presented using data collected by the LHCb detector. The polarization is studied using the decay Lambda -> p pi(-) together with its charge conjugated process, the integrated values measured are P-Lambda = 0.029 +/- 0.019 (stat) +/- 0.012 (syst), P-(Lambda) over bar = 0.003 +/- 0.023 (stat) +/- 0.014 (syst). Furthermore, the results are shown as a function of the Feynman x variable, transverse momentum, pseudorapidity and rapidity of the hyperons, and are compared with previous measurements. |
