We present a multi-target search in dwarf spheroidal galaxies for branon DM annihilation signatures with a total exposure of 354 hours with the ground-based gamma-ray telescope system MAGIC. This search led to the most constraining limits on branon DM in the sub-TeV and multi-TeV DM mass range. Our most stringent limit on the thermally-averaged annihilation cross-section (at 95% confidence level) corresponds to ⟨σv⟩ ≃ 1.9 × 10-24 cm3s-1 at a branon mass of ∼ 1.5 TeV.engAttribution 4.0 Internationalhttp://creativecommons.org/licenses/by/4.0/journal articlehttps://dx.doi.org/10.1088/1475-7516/2025/03/020https://iopscience.iop.org/article/10.1088/1475-7516/2025/03/020open access52-33Cosmology of theories beyond the SMDark matter experimentsGamma ray experimentsAstrofísica21 Astronomía y Astrofísica
