Combined search in dwarf spheroidal galaxies for branon dark matter annihilation signatures with the MAGIC telescopes

Massive brane fluctuations, called branons, behave as weakly interacting massive particles, which is one of the most favored class of candidates to fulfill the role of the dark matter (DM), an elusive kind of matter beyond the Standard Model. We present a multi-target search in dwarf spheroidal gala...
