Synchrotron self-Compton process for constraining sub-GeV dark matter in Omega Centauri via SKA
Guan-Sen Wang, Bing-Yu Su, Yang Yu +2
The search for the particle identity of dark matter (DM) continues to be a primary objective in modern physics. In this field, the sub-GeV mass range of DM detection remains a cruc…
New Constraints on Cosmic-ray boosted Sub-GeV Dark Matter via Light Mediators
Yang Yu, Guan-Sen Wang, Bo Zhang +3
Traditional direct detection experiments lack the sensitivity to probe the sub-GeV dark matter (DM), primarily due to the low energy of the expected nuclear recoils. In this work,…
Exploring sub-GeV Dark Matter Physics with Cosmic Ray and Future Telescopes
Guansen Wang, Bing-Yu Su, Lei Zu +1
If sub-GeV Dark matter(DM) annihilates to the charged particles such as , , or , it generates an additional source of electrons and positrons in the…
Primordial black holes from the ultraslow-roll phase in the inflaton--curvaton mixed field inflation
Bing-Yu Su, Nan Li, Lei Feng
Primordial black holes (PBHs) are a promising candidate for dark matter, as they can form in the very early universe without invoking new particle physics. This work explores PBH f…
