Differential Equations for Massive Correlators
Daniel Baumann, Austin Joyce, Hayden Lee +1
We uncover a combinatorial structure governing the differential equations satisfied by wavefunction coefficients of scalar fields with generic masses in de Sitter space. Using an i…

Primordial Physics in the Nonlinear Universe: mapping cosmological collider models to weak-lensing observables
Dhayaa Anbajagane, Hayden Lee
Primordial non-Gaussianities (PNGs) are features in the initial density field that provide a window into the nonlinear dynamics of particles during the inflationary epoch. Among th…

Primordial Physics in the Nonlinear Universe: signatures of inflationary resonances, excitations, and scale dependence
Dhayaa Anbajagane, Hayden Lee
Primordial non-Gaussianities (PNGs) are imprints in the initial density field sourced by the dynamics of inflation. These dynamics can induce scale dependence, oscillations, and ot…
