Measurement of the transverse polarization of Λ and Λ¯ hyperons produced in proton-proton collisions at √s = 7 TeV using the ATLAS detector

The transverse polarization of Λ and Λ¯ hyperons produced in proton-proton collisions at a center-of-mass energy of 7 TeV is measured. The analysis uses 760 μb<sup>-1</sup> of minimum bias data collected by the ATLAS detector at the LHC in the year 2010. The measured transverse polarizat...

description	The transverse polarization of Λ and Λ¯ hyperons produced in proton-proton collisions at a center-of-mass energy of 7 TeV is measured. The analysis uses 760 μb<sup>-1</sup> of minimum bias data collected by the ATLAS detector at the LHC in the year 2010. The measured transverse polarization averaged over Feynman x<sub>F</sub> from 5×10-5 to 0.01 and transverse momentum p<sub>T</sub> from 0.8 to 15 GeV is -0.010±0.005(stat)±0.004(syst) for Λ and 0.002±0.006(stat)±0.004(syst) for Λ¯. It is also measured as a function of x<sub>F</sub> and p<sub>T</sub>, 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 x<sub>F</sub> range covered by this measurement.
