Phys. Rev. D 76, 044005 (2007) [5 pages]QCD and spin effects in black hole air showersReceived 26 April 2007; published 8 August 2007 In models with large extra dimensions, black holes may be produced in high-energy particle collisions. We revisit the physics of black hole formation in extensive air showers from ultrahigh-energy cosmic rays, focusing on collisional QCD and black hole emissivity effects. New results for rotating black holes are presented. Monte Carlo simulations show that QCD effects and black hole spin produce no observable signatures in air showers. These results further confirm that the main characteristics of black hole-induced air showers do not depend on the fine details of micro-black-hole models. © 2007 The American Physical Society URL:
