- Summary:
- Polarized Z° decays into three jets have been detected and measured in the SLD (SLAC Large Detector) experiment at the Stanford Linear Accelerator Center (SLAC). The hadrons from the jets were detected in the SLD liquid argon calorimeter, providing a sensitivity over 98% of the solid angle. The spin of the gluon was tested by studying the scaled jet energies (x₁, x₂, x₃) the Ellis-Karliner angle (cosθ{sub EK}) and the parameters of event plane orientation (α, α{sub N} χ). These measured variables are compared with quantum chromodynamics (QCD) and a scalar gluon model. Good agreement is found between data and the vector QCD model for the distributions of x₁, x₂, x₃ and cosθ{sub EK}.
