With a focus on scalar effective theories, this analysis is fulfilled by introducing an integral operation acting in the Mellin space that triggers a recursive construction from diagrams at lower loops to those at higher. This gives rise to a convenient representation for arbitrary scalar diagrams, based on which analytic properties of the amplitudes can be studied systematically. I will provide several simple applications at one and two loops, and further comment on some universal features on the structure of Mellin amplitudes thus observed. | Contact Person 所内联系人 | Song He |
