Feasibility of Beauty Baryon Polarization Measurement in Lambda0 J/psi   Decay Channel by Atlas-LHC
  The possibility of beauty baryon polarization measurement by cascade decay angular distribution analysis in the channel Lambda0 J/psi --> p pi- l+ l- is demonstrated. The error analysis shows that in the proposed LHC experiment ATLAS at the luminosity $10^{4} pb^{-1}$ the polarization can be measured with the statistical precision better than $\delta=0.010$ for Lambda_b0 and $\delta=0.17$ for Xi_b0.
