The Correlation Between the Transverse Polarization andTransverse Momentum of Lambda Produced in RelativisticNucleus-Nucleus Collisions

  • The transverse polarization of lambda produced in relativistic nucleus-nucleus collisions is determined. The effect from the interaction between spin moment and magnetic field is corrected. The near zero transverse polarization and non-correlation between transverse polarization and transverse momentum are obtained and compared to ones obtained from the nucleus-nucleus interactions at lower energies. This comparison shows that the production mechanism of lambda in the relativistic nucleus-nucleus collisions is different from one in the nucleus-nucleus reactions at lower energies.

Abstract: The transverse polarization of lambda produced in relativistic nucleus-nucleus collisions is determined. The effect from the interaction between spin moment and magnetic field is corrected. The near zero transverse polarization and non-correlation between transverse polarization and transverse momentum are obtained and compared to ones obtained from the nucleus-nucleus interactions at lower energies. This comparison shows that the production mechanism of lambda in the relativistic nucleus-nucleus collisions is different from one in the nucleus-nucleus reactions at lower energies.
