Gamma-ray observations of the Galactic Center (GC) region provide some of the most sensitive measurements of annihilation signals from dark matter in the GeV-TeV mass range.
We present the first results from 178 hours of VERITAS observations of a 2 degree region around the GC, taken between 2010 and 2022.
The analysis uses a newly-developed template-based background method, as well as analysis techniques optimized for observations taken at large zenith angles.
No significant excess is found in any region of interest considered.
We derive model-independent limits on the dark matter thermally-averaged annihilation cross section which are among the strongest from any indirect detection experiment for TeV-scale masses.
