Lambda polarization in the K- fragmentation region

Results on Λ polarization in the inclusive reaction K − p→ Λ + X at 12 and 16 GeV/ c for 0.6< x <1.0, are presented. These results, obtained with the CERN Omega Spectrometer, show that the polarization is important at large x and increases with p t over the covered range 0< p t <1.2 GeV/...

description Results on Λ polarization in the inclusive reaction K − p→ Λ + X at 12 and 16 GeV/ c for 0.6< x <1.0, are presented. These results, obtained with the CERN Omega Spectrometer, show that the polarization is important at large x and increases with p t over the covered range 0< p t <1.2 GeV/ c . The average polarization for 31 857 lambdas with x >0.6 is P Λ = 0.35 ± 0.02, along the direction K − × Λ . The polarization can be expressed as P ( x , p t ) = (0.66±0.03) p t independent of x in the range covered by the experiment.
