About detecting very low mass black holes in LAr detectors

Understand

The nature of dark matter is still an open problem.

• The simplest assumption is that gravity is the only force coupled certainly to dark matter and thus the micro black holes could be a viable candidate.
• We investigated the possibility of direct detection of micro black holes with masses around and upward the Planck scale (10$^{-5}$ g), ensuring classical gravitational treatment of these objects in the next generation of huge LAr detectors.
• We show that the signals (ionization and scintillation) produced in LAr enable the discrimination between micro black holes or other particles.
