Search for dark matter using diffuse gamma rays discovered by Tibet AS-gamma

Speaker(s) Tarak Nath Maity (IISc, India)

Gamma rays being charge-neutral are extremely useful messengers in astroparticle physics. Recently the Tibet AS-gamma experiment has detected sub-PeV diffuse gamma rays from part of the galactic disc. In this talk, we will present the theorist’s view on the detection principle of high-energy gamma rays by Tibet AS-gamma. Then we will discuss its implications in the physics of particle dark matter.
