Abstract
Data collected at LEP at centre-of-mass energies root s = 189-209 GeVare used to study correlations of the spin of W bosons using e(+)e(-) -> W+W- -> lvq (q) over bar events. Spin correlations are favoured by data, and found to agree with the Standard Model predictions. In addition, correlations between the W-boson decay planes are studied in e(+)e(-) -> W+W- -> lvq (q) over bar and e(+)e(-) -> W+W- -> q (q) over barq (q) over bar events. Decay-plane correlations are measured to be consistent with the Standard Model predictions.
