相互作用的大质量自旋-1场在宇宙学和粒子物理学中有着广泛的应用。对于存在于向量场分量的非平凡约束，我们得到了这些理论经典极限的有效性的一个新条件。违反这种一致性条件会导致辅助分量的时间导数出现奇点，并可能影响，例如，场的宇宙历史和黑洞周围的超辐射。我们证明了规范不变的相互作用通常是安全的，即使质量项明确地打破了规范对称。这种相互作用的限制预计在许多其他非平凡约束系统中普遍存在。
Interacting massive spin-1 fields have been widely used in cosmology and particle physics. We obtain a new condition on the validity of the classical limit of these theories related to the nontrivial constraints that exist for vector field components. A violation of this consistency condition causes a singularity in the time derivative of the auxiliary component and could impact, for example, the field's cosmic history and superradiance around black holes. We show that gauge-invariant interactions are generally safe from this problem, even though the mass term explicitly breaks the gauge symmetry. Such restrictions for interactions are expected to exist generically in many other nontrivially constrained systems.
