Abstract: (Springer)
Data from e+e− annihilation into hadrons, taken with the ALEPH detector at the Z resonance, are analyzed. The four-jet rate is studied as a function of th- electron positron: colliding beams
- electron positron: annihilation
- Z0: electroproduction
- Z0: hadronic decay
- jet: multiple production
- yield: (4jet)
- angular correlation: (4jet)
- strong interaction: coupling constant
- color
- jet: resolution
