The transverse polarization of LAMBDA and LAMBDABAR hyperons produced in proton-proton collisions at a center-of-mass energy of 7 TeV is measured. The analysis uses $760 \\mu{}b^{-1}$ of minimum bias data collected by the ATLAS detector at the LHC in the year 2010. The measured transverse polarization averaged over Feynman xF from $5 \\times 10^{-5}$ to 0.01 and transverse momentum pT from 0.8 to 15 GeV is $-0.010 \\pm 0.005(stat) \\pm 0.004(syst)$ for LAMBDA and $0.002 \\pm 0.006(stat) \\pm 0.004(syst)$ for LAMBDABAR. It is also measured as a function of xF and pT, but no significant dependence on these variables is observed. Prior to this measurement, the polarization was measured at fixed-target experiments with center-of-mass energies up to about 40 GeV. The ATLAS results are compatible with the extrapolation of a fit from previous measurements to the xF range covered by this measurement.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.66547.v1/t1","@type":"Dataset","description":"Transverse polarization POL of LAMBDA and LAMBDABAR hyperons averaged over PT and XF.","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.66547.v1/t2","@type":"Dataset","description":"Transverse polarization POL of LAMBDA and LAMBDABAR hyperons as a function of XF.","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.66547.v1/t3","@type":"Dataset","description":"Transverse polarization POL of LAMBDA and LAMBDABAR hyperons as a function of PT.","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.66547.v1/t4","@type":"Dataset","description":"The LAMBDA reconstruction and selection efficiency EFF as a function of PT and XF.","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.66547.v1/t5","@type":"Dataset","description":"The LAMBDABAR reconstruction and selection efficiency EFF as a function of PT and XF.","name":"Table 5"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1332748?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/66547"}],"inLanguage":"en","name":"Measurement of the transverse polarization of $\\Lambda$ and $\\bar{\\Lambda}$ hyperons produced in proton-proton collisions at $\\sqrt{s}=7$ TeV using the ATLAS detector","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1332748?version=1","version":1}
