Study of Λ-production in central nucleus-nucleus interactions at the momentum of 4.6 GeV/c per incident nucleon
Description
Transverse momenta and rapidities of Λ particles produced in central nucleus-nucleus collisions at 4.5 GeV/c per nucleon (cC, CNe, ONe, CCu, CZr, CPb, OPb) have been studied and compared with those from ineiolastic He-Li interactns at the same incident momentum. Polarization of Λ hyperons was found to be consistent (within the errors) with zero (αP=-0.06+-0.11) for 224 Λ particles from central collisions. The upper limit of anti Λ/Λ production ratio was estimated to be less than 10-2 at a 90% confidence level. The analyzed experimental data were obtained using the triggered 2 m streamer spectrometer SKM-200
