摘要

晶格计算使我们能够利用第一性原理数值方法探测QCD的低洼、非微扰谱。在这里，我们提出了具有真空量子数的标量扇区的低洼谱，包括首次在完全动态QCD中胶球、q-qbar和介子-介子算子之间的混合。

Spectroscopy from the lattice: The scalar glueball

Lattice calculations allow us to probe the low-lying, non-perturbative spectrum of QCD using first principles numerical methods. Here we present the low-lying spectrum in the scalar sector with vacuum quantum numbers including, in fully dynamical QCD for the first time, the mixing between glueball, q-qbar, and meson-meson operators.
