Gluon scattering on the self-dual dyon
Tim Adamo, Giuseppe Bogna, Lionel Mason +1
The computation of scattering amplitudes in the presence of non-trivial background gauge fields is an important but extremely difficult problem in quantum field theory. In even the…

On AdS deformations of celestial symmetries
Roland Bittleston, Giuseppe Bogna, Simon Heuveline +3
Celestial holography has led to the discovery of new symmetry algebras arising from the study of collinear limits of perturbative gravity amplitudes in flat space. We explain from…

Yang-Mills form factors on self-dual backgrounds
Giuseppe Bogna, Lionel Mason
The construction of perturbative quantities on non-linear backgrounds leads to the possibility of incorporating strong field effects in perturbation theory. We continue a programme…
