【摘要】

The Cherenkov Telescope Array (CTA) is the next generation Imaging Air Cherenkov Telescope planned for the next decade and beyond. It will probe the sky in the 20 GeV to 300 TeV energy range with excellent energy and angular resolutions and up to an order of magnitude improvement in sensitivity as compared to currently operating instruments, as VERITAS, H.E.S.S. and MAGIC. CTA will address a wide range of fundamental questions in and beyond astrophysics, with covering the major aspects of cosmic particle acceleration, exploring the extreme universe and probing frontiers in physics. Especially for dark matter searches, CTA is expected to probe heavier dark matter with unprecedented sensitivity, reaching the thermal annihilation cross-section at TeV regime. The talk will first introduce and report the recent status of the project, summarize the planned dark matter search strategies with CTA, focusing on the signal from the Galactic center, and update the current collaboration effort to study the impact of diffuse astrophysical backgrounds and systematic uncertainties on the searches.
