- Detecting Axion-Like Particles with Primordial Black Holes
- Time: 1:00 pm - 2:30 pm
- Place: Chamberlin 5280
- Speaker: Tao Xu, Oklahoma U.
- Abstract: Primordial black holes, which may constitute some or all of the dark matter today, offer a fascinating opportunity to explore the physics of our universe. One unique feature of primordial black holes is their Hawking radiation process, which can produce new particles that may be secluded from the Standard Model sector. Future gamma-ray experiments, such as the e-ASTROGAM and AMEGO telescopes, provide exciting prospects for detecting the Hawking radiation signal. In this talk, I will introduce the indirect detection search for primordial black holes and discuss how the gamma-ray spectra can be used to detect axion-like particles. By analyzing the gamma-ray energy distribution, we will see that the axion-like particle decay can modify the Hawking radiation spectrum relative to the Standard Model prediction. These observations will offer a new method to probe the parameters of axion-like particle mass and photon coupling.
