Circumstellar Medium of Supernovae as New Probes for Feebly-interacting Particles
Yu Cheng, Chui-Fan Kong, Yen-Hsun Lin +2
We propose a novel strategy to probe feebly-interacting particles (FIPs) by exploiting the dense, confined circumstellar medium (CSM) surrounding core-collapse supernovae (CCSNe).…

Sommerfeld Enhancement from Background Force and the Galactic Center GeV Excess
Yu Cheng, Shuailiang Ge
We study the impact of background-induced forces on dark matter (DM) annihilation and their implications for indirect detection. In the presence of a finite number density of backg…

Background-Enhanced Axion Force by Axion Dark Matter
Yu Cheng, Shuailiang Ge
We investigate the influence of axion dark matter as a background on the spin-independent axion forces between nucleons. Notably, we find that the potential for axion forces scales…
