Phys. Rev. D 68, 104025 (2003) [6 pages]Updated limits on TeV-scale gravity from the absence of neutrino cosmic ray showers mediated by black holesReceived 24 July 2003; published 24 November 2003 We revise existing limits on the D-dimensional Planck scale MD from the nonobservation of microscopic black holes produced by high energy cosmic neutrinos in scenarios with D=4+n large extra dimensions. Previous studies have neglected the energy radiated in gravitational waves by the multipole moments of the incoming shock waves. We include the effects of energy loss, as well as form factors for black hole production and recent null results from cosmic ray detectors. For n>~5, we obtain MD>1.0–1.4TeV. These bounds are among the most stringent and conservative to date. © 2003 The American Physical Society URL:
