论文摘要
事件生成器beec [Z. Yang，X.G。吴和X.Y.王，计算。物理。社区。 184，2848（2013）]致力于在一个不算力的电子峰撞机上模拟沉重的Quarkonium生产。我们在此处升级了用极化电子和正电子束添加Quarkonium的产生。此外，还包括了2S波态的生产。在过去的十年中，讨论了具有高光度的未来几个具有高亮度的电子峰山液壁。尤其是，它们产生两极分化束的可能性对于提供对基础物理学的更多见解很重要。该升级版本为实验方面的Quarkonium的可行性研究提供了有用的工具。
The event generator BEEC [Z. Yang, X.G. Wu and X.Y. Wang, Comput. Phys. Commun. 184, 2848 (2013)] was devoted to the simulation of heavy quarkonium production at an unpolarized electron-positron collider. We upgraded it here by adding the generation of quarkonium with polarized electron and positron beams. In addition, the production of color-singlet 2S-wave states were included. Several future electron-positron colliders with high luminosity have been under discussion in the past decade. Especially, their possibility of producing polarized beams is important for providing more insights into the underlying physics. This upgraded version offers a useful tool for the feasibility study on quarkonium from the experimental side.
