  We study stars in the brane-world by employing the principle of minimal
geometric deformation and find that brane-world black hole metrics with a tidal
charge are consistently recovered in a suitable limit. This procedure allows us
to determine the tidal charge as a function of the black hole ADM mass (and
brane tension). A minimum mass for semiclassical microscopic black holes can
then be derived, with a relevant impact for the description of black hole
events at the LHC.
