WIMP Meets ALP: Coherent Freeze-Out of Dark Matter
Steven Ferrante, Maxim Perelstein, Bingrong Yu
We consider the cosmological history of a weakly interacting massive particle (WIMP) coupled to a light axion-like particle (ALP) via a quadratic coupling. Although the coupling is…
Collider Searches for Near-Continuum Dark Matter
Steven Ferrante, Lillian Luo, Maxim Perelstein +1
We study collider constraints on the near-continuum dark matter model, in which the dark sector consists of a tower of closely spaced states with weak-scale masses coupled to the S…
Sommerfeld Enhancement from Quantum Forces for Dark Matter
Steven Ferrante, Maxim Perelstein, Bingrong Yu
Quantum forces are long-range interactions that arise only at the loop level. In this work, we study the Sommerfeld enhancement of dark matter (DM) annihilation cross sections caus…
Holographic Energy Correlators for Soft Walls
Csaba Csáki, Steven Ferrante, Ameen Ismail
We calculate energy correlators in a general holographic model of confinement, involving an asymptotically anti-de Sitter (AdS) warped extra dimension. Building on a recent computa…
