A collider test of nano-Hertz gravitational waves from pulsar timing arrays
Shao-Ping Li, Ke-Pan Xie
A cosmic first-order phase transition (FOPT) occurring at MeV-scale provides an attractive explanation for the nano-Hertz gravitational wave (GW) background indicated by the recent…
Self-interacting dark matter implied by nano-Hertz gravitational waves
Chengcheng Han, Ke-Pan Xie, Jin Min Yang +1
The self-interacting dark matter (SIDM) paradigm offers a potential solution to the small-scale structure problems faced by collision-less cold dark matter. This framework incorpor…
Freeze-in of WIMP dark matter
Xiao-Rui Wang, Ke-Pan Xie
The nature of dark matter (DM) remains one of the most important unanswered questions in particle physics. Here, we propose a novel scenario for DM in which weakly interacting mass…
Pinning down the primordial black hole formation mechanism with gamma-rays and gravitational waves
Ke-Pan Xie
Primordial black holes (PBHs) are predicted in many models via different formation mechanisms. Identifying the origin of PBHs is of the same importance as probing their existence.…
