SUMMARY:Detecting Axion-Like Particles with Primordial Black Holes\, T
 heory Seminar (High Energy/Cosmology)\, Tao Xu\, Oklahoma U.
DESCRIPTION: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 ho
 les is their Hawking radiation process\, which can produce new particl
 es that may be secluded from the Standard Model sector. Future gamma-r
 ay experiments\, such as the e-ASTROGAM and AMEGO telescopes\, provide
  exciting prospects for detecting the Hawking radiation signal. In thi
 s talk\, I will introduce the indirect detection search for primordial
  black holes and discuss how the gamma-ray spectra can be used to dete
 ct axion-like particles. By analyzing the gamma-ray energy distributio
 n\, we will see that the axion-like particle decay can modify the Hawk
 ing radiation spectrum relative to the Standard Model prediction. Thes
 e observations will offer a new method to probe the parameters of axio
 n-like particle mass and photon coupling.
