在排他B衰变中寻找标量胶球

Hunting for a scalar glueball in exclusive B decays

Cai-Dian Lü, Ulf-G. Meißner, Wei Wang, Qiang Zhao

摘要:

利用已得到实验验证的轻夸克味SU(3)对称性,我们提出了一种在B衰变中寻找标量胶球的直观方法。在胶球与普通标量介子混合的情况下,我们探讨了混合参数的提取。特别是,我们讨论了最近可用的实验数据的含义,并显示作为探针的标量结构的B衰变的灵敏度。未来的超级KEKB工厂将允许建立标量之间的混合模式,并可能允许人们解开QCD预测的标量胶球的存在和混合的长期困惑。

英文摘要:

Using flavor SU(3) symmetry for the light quarks validated by the available experimental data, we propose an intuitive way to hunt for a scalar glueball in B decays. In the presence of mixing between the glueball and ordinary scalar mesons, we explore the extraction of the mixing parameters. In particular, we discuss the implication from the recently available experimental data and show the sensitivities of B decays as a probe to the scalar structures. The future Super KEKB factory would allow access to establishing the mixing pattern among the scalars, and possibly allow one to disentangle the long-standing puzzle concerning the existence and mixings of the scalar glueball predicted by QCD.
