Ultrarelativistic Particle Collisions
Abstract
We present results from numerical solution of the Einstein field equations describing the headon collision of two solitons boosted to ultrarelativistic energies. We show, for the first time, that at sufficiently high energies the collision leads to black hole formation, consistent with hoopconjecture arguments. This implies that the nonlinear gravitational interaction between the kinetic energy of the solitons causes gravitational collapse, and that arguments for black hole formation in superPlanck scale particle collisions are robust.
