Deformed ₁₊∞ Algebras in the Celestial CFT
We compute the modification of the ₁₊∞ algebra of soft graviton, gluon, and scalar currents in the celestial CFT due to non-minimal couplings. We find that the Jacobi identity is satisfied only when the spectrum and couplings of the theory obey certain constraints. We comment on the similarities and...

Digital Library of Periodicals of National Academy of Sciences of Ukraine| Summary: | We compute the modification of the ₁₊∞ algebra of soft graviton, gluon, and scalar currents in the celestial CFT due to non-minimal couplings. We find that the Jacobi identity is satisfied only when the spectrum and couplings of the theory obey certain constraints. We comment on the similarities and essential differences between this algebra and ₁₊∞.
