Black hole formation in the grazing collision of high-energy particles

Research output: Chapter in Book/Report/Conference proceedingChapter


We numerically investigate the formation of black holes in high-energy particle collision with an impact parameter in D-dimensional spacetimes and evaluate the total cross section of the black hole production. We find that the formation of the apparent horizon occurs when the distance between the colliding particles is less than 1.5 times the effective gravitational radius of each particle. Our numerical result indicates that the characteristic (D – 3)-dimensional volume of the system provides a condition to approximately estimate the maximal impact parameter for the apparent horizon formation.
