Maths HEP Lunchtime Seminars: Mellin amplitudes and their applications

Presented by Miguel Paulos, Jussieu

17 February 2012 13:00 in CM221

We introduce the Mellin transform for conformally invariant correlation
functions. Mellin amplitudes have simple analytic properties, and are
functions of quantities resembling higher dimensional momenta. For theories
with a lagrangian description, Mellin amplitudes satisfy a set of simple
Feynman rules, which solve the theories at tree-level. We apply this
formalism to correlators of scalar field theories and also the AdS/CFT
