  Abstract The transverse polarization of Lambda and (Lambda) over bar 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 < p(T) < 6.00 GeV/c, and Feynman-x in the ranges 0.005 < x(F) < 0.040 (forward region) and -0.10 < x(F) < -0.01 (backward region) defined relative to the proton beam direction. The transverse polarization is found to be compatible with zero for both Lambda and and (Lambda) over bar hyperons. The results are also measured as a function of p(T) and x(F) with no significant dependence on these variables observed. The results are compared with previous experimental measurements at different centerof-mass energies and collision environments.
