论文摘要
我们提出了与任何时空维度中与任何骨无质量粒子相关的保守渐近电荷的统一处理。特别是，我们为相应的电荷代数中的渐近电荷和中央扩展提供了主公式。这些公式可以针对任何给定理论明确评估。为了说明，我们将它们应用于电磁和重力，从而恢复了早期的结果。
We present a unified treatment of the conserved asymptotic charges associated with any bosonic massless particle in any spacetime dimension. In particular we provide master formulae for the asymptotic charges and the central extensions in the corresponding charge algebras. These formulae can be explicitly evaluated for any given theory. For illustration we apply them to electromagnetism and gravity, thereby recovering earlier results.
