The significance of polarization by combining the seven energy points is found to be 2.6 sigma including the systematic uncertainty, which implies a non-zero phase between the transition amplitudes of the Lambda(Lambda) over bar helicity states. The modulus ratio and the relative phase of EM-psionic form factors combined with all energy points are measured to be R-Psi = 0.71(-0.10)(+0.10) +/- 0.03 and Delta Phi(Psi) = 23(-8.0)(+8.8) +/- 1.6 degrees, where the first uncertainties are statistical and the second systematic.eninfo:eu-repo/semantics/openAccessE(+)-E(-) ExperimentsElectroweak InteractionPolarizationArticle10WOS:0010932251000012-s2.0-85174277787N/A10.1007/JHEP10(2023)081Q2
