Probing the Galactic Center region with ground-based Cherenkov telescopes enables the search for TeV spectral features in immediate association with a dense dark matter reservoir at a sensitivity out of reach for satellite γ -ray detectors, and direct detection and collider experiments. We report on 223 hours of observations of the Galactic Center region with the MAGIC stereoscopic telescope system reaching γ -ray energies up to 100 TeV. We improved the sensitivity to spectral lines at high energies using large-zenith-angle observations and a novel background modeling method within a maximum-likelihood analysis in the energy domain. No linelike spectral feature is found in our analysis. Therefore, we constrain the cross section for dark matter annihilation into two photons to ⟨σ v ⟩≲5 ×10-28 cm3 s-1 at 1 TeV and ⟨σ v ⟩≲1 ×10-25 cm3 s-1 at 100 TeV, achieving the best limits to date for a dark matter mass above 20 TeV and a cuspy dark matter profile at the Galactic Center. Finally, we use the derived limits for both cuspy and cored dark matter profiles to constrain supersymmetric wino models.STAMPAenSearch for Gamma-Ray Spectral Lines from Dark Matter Annihilation up to 100 TeV toward the Galactic Center with MAGICArticle10.1103/PhysRevLett.130.0610022-s2.0-85148450343https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.130.061002http://arxiv.org/abs/2212.10527v12023PhRvL.130f1002AFIS/05 - ASTRONOMIA E ASTROFISICA
