关于重夸克偶素强子产生的机制

On the mechanisms of heavy-quarkonium hadroproduction

J. P. Lansberg

摘要:

我们讨论了在色单重态(CS)和色八重态(CO)通道中的高阶QCD修正的计算以及CS通道中s通道切割的贡献,讨论了在重夸克偶素强子产生中可能起作用的各种机制.我们还讨论了新的观测意味着更好地区分这些不同的机制。

英文摘要:

We discuss the various mechanisms potentially at work in hadroproduction of heavy quarkonia in the light of computations of higher-order QCD corrections both in the Colour-Singlet (CS) and Colour-Octet (CO) channels and the inclusion of the contribution arising from the s-channel cut in the CS channel. We also discuss new observables meant to better discriminate between these different mechanisms.
