论文摘要
假设单位性，局部性，因果关系和洛伦兹（Lorentz）的不变性，否则未知的紫外线完成，我们为有效的现场理论系数提供了一套新的约束，以获得最一般的，无鬼的广义proca和proca nuevo nuevo massive massive vector模型。对于广义的Proca模型，我们包括以前在阳性界面上没有考虑过的新交互作用，并找到这些额外的术语会导致以前考虑的相互作用的参数空间扩大。虽然，广义的proca和proca nuevo模型是不相等的，但我们在参数化两个模型的系数与它们在阳性范围中扮演的角色之间的有趣类似物。
Assuming unitarity, locality, causality, and Lorentz invariance of the, otherwise unknown, UV completion, we derive a new set of constraints on the effective field theory coefficients for the most general, ghost-free Generalized Proca and Proca Nuevo massive vector models. For the Generalized Proca model, we include new interactions that had not been previously considered in the context of positivity bounds and find these additional terms lead to a widened parameter space for the previously considered interactions. Although, the Generalized Proca and Proca Nuevo models are inequivalent, we find interesting analogues between the coefficients parameterizing the two models and the roles they play in the positivity bounds.
