Transverse polarization measurement of Λ hyperons in pNe collisions at √sNN = 68.4 GeV with the LHCb detector
A measurement of the transverse polarization of the Λ andΛ hyperons in pNe fxed-target collisions at √ sNN = 68.4 GeV is presented using data collected by the LHCb detector. The polarization is studied using the decay Λ → pπ− together with its charge conjugated process, the integrated values mea...

| description | A measurement of the transverse polarization of the Λ andΛ hyperons in pNe
fxed-target collisions at √
sNN = 68.4 GeV is presented using data collected by the LHCb
detector. The polarization is studied using the decay Λ → pπ− together with its charge
conjugated process, the integrated values measured are
PΛ = 0.029 ± 0.019 (stat) ± 0.012 (syst),
PΛ = 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. |
