Probing Confining Dark Sectors with Cosmological Perturbations
Daven Wei Ren Ho, Ameen Ismail, Yuhsin Tsai
Dark matter may emerge as a composite state of a dark sector which confines in a strongly first-order phase transition (PT). To avoid structure formation constraints on warm dark m…
Ultralight Dilatonic Dark Matter
Abhishek Banerjee, Csaba Csáki, Michael Geller +2
The dilaton, a pseudo-Nambu-Goldstone boson (pNGB) of broken scale invariance, is an appealing ultralight dark matter (DM) candidate. Its mass is protected by conformal invariance…
Axion dark matter from inflation-driven quantum phase transition
Ameen Ismail, Seung J. Lee, Bingrong Yu
We propose a new mechanism to produce axion dark matter from inflationary fluctuations. Quantum fluctuations during inflation are strengthened by a coupling of the axion kinetic te…
