量子色动力学中的胶子存在强耦合自相互作用，这表明存在胶子场起关键作用的强子：胶球（无夸克参与、由胶子结合形成的强子）和混杂态（激发的胶子场与夸克耦合形成的强子）。本章介绍了当代对这类态的理论理解，以及在实验强子谱中明确识别它们存在所面临的挑战。
英文摘要
That the gluons of quantum chromodynamics self-interact with a strong coupling suggests the possibility of hadrons in which the gluonic field plays an essential role: Glueballs in which gluons stick together to produce a hadron in which no quarks are required, and hybrids in which an excited gluonic field couples to quarks. This chapter presents our contemporary theoretical understanding of such states, and the challenges associated with definitively identifying their presence within the experimental spectrum of hadrons.
