We conduct an indirect dark matter (DM) search in the vicinity of the Galactic Center, focusing on a square region within ±9° in Galactic longitude and latutide, using 2865 days of data (∼8 yr) from the High-Altitude Water Cherenkov (HAWC) Observatory. We explore DM particles within the weakly interacting massive particles framework with masses from 1 TeV to 10 PeV. Analyzing three annihilation channels (bb¯, τ+τ-, W+W-) and three density profiles (Navarro-Frenk-White, Einasto, Burkert), we find no significant excess and set 95% CL upper limits on the velocity-weighted annihilation cross section. Our results provide the first constraints on DM particles well above 100 TeV using gamma-ray data from the vicinity of the Galactic Center, with the strongest limits O(10-24) cm3/s, from the τ+τ- channel and the Einasto profile.
