摘要

We compute the modification of the w1+& INFIN; 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 con-straints. We comment on the similarities and essential differences of this algebra to W1+& INFIN;.
