Charged Loops at the Cosmological Collider with Chemical Potential
Arushi Bodas, Edward Broadberry, Raman Sundrum +1
Cosmological collider physics allows the detection of heavy particles at inflationary scales through their imprints on primordial non-Gaussianities. We study the chemical potential…
Warm Inflation with Pseudo-scalar Couplings
Edward Broadberry, Anson Hook, Sagnik Mondal
Inflaton couplings during warm inflation result in the production of a thermal bath. Thermal friction and fluctuations can dominate the standard de Sitter analogues, resulting in a…
Vector Portals at Future Lepton Colliders
Sagar Airen, Edward Broadberry, Gustavo Marques-Tavares +1
We assess the sensitivity of future lepton colliders to weakly coupled vector dark portals (aka `` bosons'') with masses ranging from tens of GeV to a few TeV. Our analysis f…
Grand Unification at the Cosmological Collider with Chemical Potential
Arushi Bodas, Edward Broadberry, Raman Sundrum
We introduce a tree-level chemical potential mechanism for spin-1 particles within cosmological collider physics, allowing them to be detected in primordial non-Gaussianities for m…
Adiabatic Conversion of ALPs into Dark Photon Dark Matter
Edward Broadberry, Saurav Das, Anson Hook +1
We introduce a mechanism by which a misaligned ALP can be dynamically converted into a dark photon in the presence of a background magnetic field. An abundance of non-relativistic…
