Discovery and spectroscopy of dark matter and dark sectors with microscopic black holes at next generation colliders

If the length scale of possible extra dimensions is large enough, the effective Planck scale is lowered such that microscopic black holes could be produced in collisions of high-energy particles at colliders. These black holes evaporate through Hawking radiation of a handful of energetic particles drawn from the set of all kinematically and thermally allowed degrees of freedom, including dark matter. Here, we perform the first numerical black hole spectroscopic study of the dark sector. We find that if the next generation of colliders can produce microscopic black holes, then missing momentum signatures can reveal the existence of {any new light (≲10 {}) particle}, regardless of the strength of its coupling to the Standard Model, even if there exists no such non-gravitational coupling at all.
