Celestial diamonds: conformal multiplets in celestial CFT

چکیده
A bstract We examine the structure of global conformal multiplets in 2D celestial CFT. For a 4D bulk theory containing massless particles spin s = $$ \left\{0,\frac{1}{2},1,\frac{3}{2},2\right\} 0 1 2 3 we classify and construct all SL(2, ℂ ) primary descendants which are organized into ‘celestial diamonds’. This explicit construction is achieved using wavefunction-based approach that allows us to map scattering amplitudes CFT correlators operators with dimension ∆ J . Radiative wavefunctions have ± give rise conformally soft theorems for special values ∈ \frac{1}{2}\mathbb{Z} ℤ They located either at top diamonds, where they descend trivial null primaries, or left right corners, both from generalized | ≤ Celestial diamonds naturally incorporate degeneracies opposite helicity via shadow transform relating radiative primaries account asymptotic symmetries gauge gravity.

Thoughout this paper we use a single dot over a variable to represent its derivative with respect to time t and a double dot to represent its second derivative with respect to t. The potential energy U has a singularity whenever q(=q^ We write this singular set ^v = {€€(«?: *, = *,}, A = U Au...
متن کاملMimicking celestial mechanics in metamaterials
Einstein’s general theory of relativity establishes equality between matter–energy density and the curvature of spacetime. As a result, light and matter follow natural paths in the inherent spacetime and may experience bending and trapping in a specific region of space. So far, the interaction of light and matter with curved spacetime has been predominantly studied theoretically and through ast...
متن کاملThe Motion of Celestial Bodies
The history of celestial mechanics is first briefly surveyed, identifying the major contributors and their contributions. The Ptolemaic and Copernican world models, Kepler’s laws of planetary motion and Newton’s laws of universal gravity are presented. It is shown that the orbit of a body moving under the gravitational attraction of another body can be represented by a conic section. The six or...
