Soft limits of Yang-Mills amplitudes and conformal correlators
Soft limits of Yang-Mills amplitudes and conformal correlators
A bstract We study tree-level celestial amplitudes in Yang-Mills theory — Mellin transforms of multi-gluon scattering amplitudes that convert them into the correlators of conformal primary fields on two-dimensional celestial sphere. By using purely field-theoretical methods, we show that the soft conformal limit of celestial amplitudes, in which one of …
