天体钻石对二维天体 CFT 中的全局共形多重态结构进行编码,并提供用于描述共形软扇区的自然语言。出现在其左右角的算子产生了共形软因子分解定理,底角对应于守恒电荷,顶角对应于保形敷料。我们证明,共形软电荷可以用光线积分来表示,光线积分选择适当的共形权重的模式。它们位于记忆钻石的底角,并上升到广义电流。然后,我们用共形 Faddeev-Kulish 敷料识别相关金石钻石的顶角,并计算规范理论和重力中的次主导共形软敷料,这对于寻找非平凡的中心延伸非常重要。最后,我们结合这些成分来推测天体 CFT 共形软扇区的二维有效描述。
Celestial diamonds encode the structure of global conformal multiplets in 2D celestial CFT and offer a natural language for describing the conformally soft sector. The operators appearing at their left and right corners give rise to conformally soft factorization theorems, the bottom corners correspond to conserved charges, and the top corners to conformal dressings. We show that conformally soft charges can be expressed in terms of light ray integrals that select modes of the appropriate conformal weights. They reside at the bottom corners of memory diamonds, and ascend to generalized currents. We then identify the top corners of the associated Goldstone diamonds with conformal Faddeev-Kulish dressings and compute the sub-leading conformally soft dressings in gauge theory and gravity which are important for finding nontrivial central extensions. Finally, we combine these ingredients to speculate on 2D effective descriptions for the conformally soft sector of celestial CFT.
