Longitudinal spin transfer to Lambda and Lambda hyperons in polarized proton-proton collisions at s=200 GeV

Original language description

The longitudinal spin transfer, D-LL, from high energy polarized protons to Lambda and Lambda hyperons has been measured for the first time in proton-proton collisions at s=200 GeV with the STAR detector at the Relativistic Heavy Ion Collider. The measurements cover pseudorapidity, eta, in the range |eta|< 1.2 and transverse momenta, p(T), up to 4 GeV/c. The longitudinal spin transfer is found to be D-LL=-0.03 +/- 0.13(stat)+/- 0.04(syst) for inclusive Lambda and D-LL=-0.12 +/- 0.08(stat)+/- 0.03(syst)for inclusive Lambda hyperons with <eta >=0.5 and < p(T)>=3.7 GeV/c. The dependence on eta and p(T) is presented.
