Black hole production via quantum tunneling
Abstract
Description
Particles colliding at impact parameter much larger than the effective gravitational radius can not classically form a black hole and just scatter off the radial potential barrier separating the particles. We show that the process of the black hole production can still go quantum-mechanically via familiar mechanism of the under-barrier tunneling. The mechanism is illustrated for collision of a trans-Planckian particle and a lighter particle. Our analysis reveals instability of trans-Planckian particles against transition to the phase of black hole.
