Abstract: A bstractWe study instanton corrections to four-point correlation correlation function of half-BPS operators in N$$ \mathcal{N} $$ = 4 SYM in the light-cone limit when operators become null separated in a sequential manner. We exploit… read more here.

DOI: 10.1142/s0217751x23500653
Abstract: Using the ambitwistor string theory, we study graviton scattering amplitudes in a light-like linear dilaton background of ten-dimensional supergravity. At the tree level, we find that the three-graviton amplitude coincides with the type II superstring… read more here.

DOI: 10.2996/kmj44104
Abstract: In the authors' previous work, it was shown that if a zero mean curvature $C^4$-differentiable hypersurface in an arbitrarily given Lorentzian manifold admits a degenerate light-like point, then the hypersurface contains a light-like geodesic segment… read more here.
