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…
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…
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…
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…
