Abstract
The transverse polarization of Λ and ¯Λ hyperons is measured in 𝑝Pb collisions collected by the LHCb experiment at a nucleon-nucleon center-of-mass energy of 5.02 TeV. The polarization is averaged over hyperon transverse momentum in the range 0.15<𝑝T<6.00 GeV/𝑐, and Feynman-𝑥 in the ranges 0.005 <𝑥F <0.040 (forward region) and −0.10 <𝑥F <−0.01 (backward region) defined relative to the proton beam direction. The transverse polarization is found to be compatible with zero for both Λ and ¯Λ hyperons. The results are also measured as a function of 𝑝T and 𝑥F with no significant dependence on these variables observed. The results are compared with previous experimental measurements at different center-of-mass energies and collision environments.
