Derives PDEs for MHV celestial amplitudes in Liouville theory, computes logarithmic b² corrections, and shows the gluon OPE deformation at this order is isomorphic to the one-loop correction in pure Yang-Mills.
Restricting one helicity to the wedge sector and introducing shadow charges yields closed mixed-helicity algebras for all spins in gravity and gauge theory, plus dual mass BMS extensions and non-vanishing electromagnetic central charges.
