  Title:  From On-shell amplitude in AdS to Cosmological correlators
Abstract: We will begin by discussing the motivation and setup of Mellin-momentum amplitudes, along with several examples, including the Feynman rules and their associated pole structures. Following this, we will present the recursive on-shell bootstrap process, which is designed to compute higher-point Mellin-momentum amplitudes for YM and GR in AdS space. Additionally, the bootstrap can be used to derive the Class I soft theorem for Mellin-momentum amplitudes in a diagrammatic fashion. If time permits, we will also introduce a recursive method for finishing the bulk scalar integrals, which connects Mellin-momentum amplitudes to boundary CFT correlators. This process leads to the wavefunction coefficients through wick rotation, thereby providing the cosmological correlators. This talk is based on the works [2305.13894], [2402.09111], [2407.16052], and [2410.04875].
