چکیده
A bstract In this paper, we present a comprehensive study of ϒ inclusive production in Z boson decay, including the first complete next-to-leading-order calculations color-octet (CO) contributions. With inclusion newly-calculated remarkable QCD corrections, CO processes exhibit crucially phenomenological influence on existing predictions built color-singlet mechanism. We also include exhaustive evaluations feed-down contributions, which remained ignored literature, and find them to be considerable. Summing up all ℬ → ϒ( nS ) + X still notably undershoot data released by L3 Collaboration.

Quarkonium Production at Z and in Υ(1s) Decay
The conventional color-singlet model was challenged by the recent data on quarkonium production. Discrepancies in production rates were observed at the Tevatron, at LEP, and in fixed-target experiments. The newly advocated color-octet mechanism provides a plausible solution to the anomalous quarkonium production observed at the Tevatron. The color-octet mechanism should also affect other quarko...

متن کاملGravitational decay of the Z-boson
We study the decay process of the Z boson to a photon and a graviton. The most general form of the on-shell amplitude, subject to the constraints due to the conservation of the electromagnetic current and the energy-momentum tensor, is determined. The amplitude is expressed in terms of three form factors, two of which are CP-odd while one is CP-even. The latter, which is the only non-zero form ...
