Cosmological scattering equations at tree-level and one-loop
Abstract We recently proposed a formula for tree-level n-point correlators of massive ϕ 4 theory in de Sitter momentum space which consists of an integral over n punctures on the Riemann sphere and differential operators in the future boundary dubbed the cosmological scattering equations. This formu...
