Spin alignment in heavy and light flavour systems at OPAL
Spin alignment of inclusive vector mesons and longitudinal polarization of Lambda hyperons have been measured in a sample of 4.3 million hadronic Z/sup 0/ decays from the OPAL detector at LEP. Leading, light vector mesons have been $9 found to populate preferentially the helicity-zero state, a resul...
