电磁相互作用的大质量自旋2场:外场中的本征截止和病理
Electromagnetically Interacting Massive Spin-2 Field: Intrinsic Cutoff and Pathologies in External Fields
摘要:
利用Stueckelberg形式,我们证明了在平坦空间中与电磁场耦合的大质量自旋2场理论必须具有一个内禀的、模型无关的、有限的UV截止。我们展示了如何一个截止的存在有连接到系统的其他病变,如超光速传播。我们评论的推广结果任意自旋,引力相互作用。
英文摘要:
By employing the Stueckelberg formalism, we argue that the theory of massive spin-2 field coupled to electromagnetism in flat space must have an intrinsic, model independent, finite UV cutoff. We show how the very existence of a cutoff has connection to other pathologies of the system, such as superluminal propagation. We comment on the generalization of the results to arbitrary spin, and to gravitational interaction.
