Description
The dark matter problem is one of the most elusive problems of modern physics and several extensions of the Standard Model have been proposed to address this puzzle. One of the relevant hypotheses is known as "Weakly Interacting Massive Particles": massive particles in the GeV-TeV scale with a weak coupling to the SM sector. One of the detection approaches for WIMPs is the indirect detection method: DM particles may self-annihilate in astrophysical objects and produce an excess in the fluxes of SM particles, which can propagate and reach observatories on Earth. Gamma rays are particularly interesting among these messengers because they do not suffer propagation effects. One of the most important future gamma-ray telescopes is the Cherenkov Telescope Array Observatory (CTAO). The CTAO will increase the sensitivity of the current experiments by one order of magnitude and probe masses for thermal DM in the (0.1 - 10) TeV range, being a fundamental test for the WIMP paradigm in the future. In this talk, I will present the most important characteristics and strategies of DM indirect searches with the CTAO and the expected limits for some specific BSM theories.
