Abstract: | Data collected at LEP at centre-of-mass energies
GeV are used to study correlations of the spin of W bosons using
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
and
events. Decay-plane correlations are measured to be consistent with the Standard Model predictions.Received: 26 October 2004, Revised: 15 January 2005, Published online: 3 March 2005 |
