EXPLANATION OF THE DATA ON $\Gamma (Z^0\to b\bar b) /\Gamma (Z^0\to {\rm hadrons})$ AND THE INCLUSIVE b→sγ BRANCHING RATIO

Abstract

Calculations show that the data on the Z0 hadronic branching ratio fraction to [Formula: see text] at the Z0 pole as well as the inclusive b→sγ branching ratio can be explained by an anomalous (γ-Z0)WW coupling having ∆κ=−1 and λ=0. Such a vertex was derived from a representation in spinor space some time ago. The agreement is analyzed and possible implication of that basic spinor symmetry are described. Finally, the recent data on diboson production and their interpretation are examined critically. The used and shortly presented electroweak unification scheme of “structureless compositeness” provides two natural explanations of the increase of the inclusive jet cross-section above 200 GeV jet transverse energy observed at FNAL recently.
