赝标胶球与$η-η^\prime$混合

Pseudoscalar glueball and $η-η^\prime$ mixing

V. Mathieu, V. Vento

摘要:

我们对赝标通道中的混合进行了动力学分析,目的是了解赝标胶球的存在和行为。我们的哲学不是预测胶球质量的精确值,而是利用足够有效的理论来突破,并分析哪种机制恢复与数据的兼容性。我们的研究导致了分析的解决方案,使一个清晰的理解的现象。我们的计算结果导致一个大质量的胶球$M_Θ>2000$兆电子伏,一个大的胶含量的$η^\prime$和混合角与以前的数值研究。

英文摘要:

We have performed a dynamical analysis of the mixing in the pseudoscalar channel with the goal of understanding the existence and behavior of the pseudoscalar glueball. Our philosophy has not been to predict precise values of the glueball mass but to exploit an adequate effective theory to the point of breaking and to analyze which kind of mechanisms restore compatibility with data. Our study has lead to analytical solutions which allow a clear understanding of the phenomena. The outcome of our calculation leads to a large mass glueball $M_Θ>2000$ MeV, to a large glue content of the $η^\prime$ and to mixing angles in agreement with previous numerical studies.
