DSE/BSE框架中的淬火胶球
Quenched glueballs in the DSE/BSE framework
摘要：
从束缚态方程出发，用猝灭量子色动力学方法计算了量子数为$J^\mathsf{PC}=0^{\pm+},2^{\pm+},3^{\pm+},4^{\pm+}$的胶球的光谱。输入取自两点和三点函数的无参数计算。我们的结果与晶格结果一致，也包含一些额外的状态。对于标量胶球，我们提出了第一个结果的影响，额外的图表，原来是强烈抑制。
英文摘要：
The spectrum of glueballs with quantum numbers $J^\mathsf{PC}=0^{\pm+},2^{\pm+},3^{\pm+},4^{\pm+}$ is calculated in quenched quantum chromodynamics from bound state equations. The input is taken from a parameter-free calculation of two- and three-point functions. Our results agree well with lattice results where available and contain also some additional states. For the scalar glueball, we present first results for the effects of additional diagrams which turn out to be strongly suppressed.
