Mellin amplitude for n-gluon scattering in anti–de Sitter spacetime

Jinwei Chu (Department of Physics, University of Chicago, Chicago, Illinois 60637, USA) ; Savan Kharel (Department of Physics, University of Chicago, Chicago, Illinois 60637, USA)

In AdS/CFT, we introduce a robust method for computing n-point gluon Mellin amplitudes, applicable in various spacetime dimensions. Using the Mellin transform and a recursive algorithm, we efficiently calculate tree-level gluon amplitudes. Our approach simplifies the representation of higher-point amplitudes, eliminating the need for complicated integrations. Crucially, the resulting amplitudes closely mirror those in flat space, allowing a straightforward dictionary between the two settings circumventing explicit calculations.
