Mirror QCD phase transition as the origin of the nanohertz Stochastic Gravitational-Wave Background
Lei Zu, Chi Zhang, Yao-Yu Li +3
Several Pulsar Timing Array (PTA) collaborations have recently provided strong evidence for a nHz Stochastic Gravitational-Wave Background (SGWB). Here we investigate the implicati…

Multi-frequency test of dark matter annihilation into long-lived particles in Sirius
Yu-Xuan Chen, Lei Zu, Zi-Qing Xia +2
New long-lived particles produced at the colliders may escape from conventional particle detectors. Using satellites or ground telescopes, we can detect the photons generated from…
