The updated assessment of the power of the Cherenkov Telescope Array (CTA) reveals its potential to search for thermally produced dark matter at the TeV scale, significantly expanding the range of testable models and probing various well-motivated models with unprecedented sensitivity and resolution. CTA's survey of the inner Galaxy will map with unprecedented precision the large-scale diffuse emission in high-energy gamma rays, constituting a background for dark matter searches. Throughout the analysis, attention is paid to quantifying the level of instrumental and background template systematic uncertainties required to probe thermally produced dark matter at these energies.
We provide an updated assessment of the power of the Cherenkov Telescope Array (CTA) to search for thermally produced dark matter at the TeV scale, via the associated gamma-ray signal from pair-annihilating dark matter particles in the region around the Galactic centre. We find that CTA will open a new window of discovery potential, significantly extending the range of robustly testable models given a standard cuspy profile of the dark matter density distribution. Importantly, even for a cored profile, the projected sensitivity of CTA will be sufficient to probe various well-motivated models of thermally produced dark matter at the TeV scale. This is due to CTA's unprecedented sensitivity, angular and energy resolutions, and the planned observational strategy. The survey of the inner Galaxy will cover a much larger region than corresponding previous observational campaigns with imaging atmospheric Cherenkov telescopes. CTA will map with unprecedented precision the large-scale diffuse emission in high-energy gamma rays, constituting a background for dark matter searches for which we adopt state-of-the-art models based on current data. Throughout our analysis, we use up-to-date event reconstruction Monte Carlo tools developed by the CTA consortium, and pay special attention to quantifying the level of instrumental systematic uncertainties, as well as background template systematic errors, required to probe thermally produced dark matter at these energies.
