Mastering cosmological amplitudes using generalized Ramanujan’s theorem
Abstract We present a systematic method for computing cosmological amplitudes, including in-in correlators and wavefunction coefficients. Specialising to cases with conformally-coupled external scalars and massive scalar exchanges, we introduce a decomposition into massive family trees, which captur...
