Phys. Rev. D 66, 065004 (2002) [4 pages]High-energy head-on collisions of particles and the hoop conjectureReceived 18 April 2002; published 19 September 2002 We investigate the apparent horizon formation for high-energy head-on collisions of particles in D-dimensional spacetime. The apparent horizons formed before the instant of collision are obtained analytically. We apply the D-dimensional hoop conjecture to these solutions and show that the horizon formation becomes more difficult for larger D. © 2002 The American Physical Society URL:
