The polarisation is measured in bins of transverse momentum pT and rapidity y in the kinematic region 3.5 < pT < 15 GeV/c and 2.0 < y < 4.5, and is compared to theoretical models. No significant polarisation is observed.22 p.application/pdfengcc-by (c) Camboni, Alessandro et al., 2014https://creativecommons.org/licenses/by/4.0/HadronsGran Col·lisionador d'HadronsFísica de partículesExperimentsHadronsLarge Hadron Collider (France and Switzerland)Particle physicsExperimentsinfo:eu-repo/semantics/article6457652022-05-16info:eu-repo/semantics/openAccess
