Large p explorations. From SUGRA to big STRINGS in Mellin space

F Aprile, P Vieira - Journal of High Energy Physics, 2020 - Springer
A bstract We explore a new way of probing scattering of closed strings in AdS 5× S 5, which
we call 'the large p limit'. It consists of studying four-point correlators of single-particle …
