We discuss the counting of Nambu-Goldstone (NG) modes associated with the spontaneous breaking of higher-form global symmetries. Effective field theories of NG modes are developed based on symmetry-breaking patterns, using a generalized coset construction for higher-form symmetries. We derive a formula of the number of gapless NG modes, which involves expectation values of the commutators of conserved charges, possibly of different degrees.
我们讨论与高阶整体对称性自发破缺相关的南布-戈德斯通（NG）模式的计数。基于对称性破缺模式，利用高阶对称性的广义陪集构造，发展了NG模式的有效场论。我们推导了无质量NG模式数量的公式，该公式涉及守恒荷对易子的期望值，这些守恒荷可能具有不同的度数。
