摘要：

The possibility of beauty baryon polarization measurement by cascade decay angular distribution analysis in the channel Lambda(0)J/psi --> p pi-+- is demonstrated. The error analysis shows that in the proposed large hadron collider experiment ATLAS the polarization can be measured with an estimated statistical precision of delta = 0.010 for Lambda(b)(0) and delta = 0.17 for Xi(b)(0).
