We study the formation of a black hole in the col- lision of two Gaussian packets. Rather than following their dynamical evolution in detail, we assume a horizon forms when the mass function for the two packets becomes larger than half the flat areal radius, as it would occur in a spher- ically symmetric geometry. This simple approximation al- lows us to determine the existence of a minimum black hole mass solely related to the width of the packets. We then com- ment on the possible physical implications, both in classical and quantum physics, and models with extra spatial dimen- sions.

Abstract
We study the formation of a black hole in the col- lision of two Gaussian packets. Rather than following their dynamical evolution in detail, we assume a horizon forms when the mass function for the two packets becomes larger than half the flat areal radius, as it would occur in a spher- ically symmetric geometry. This simple approximation al- lows us to determine the existence of a minimum black hole mass solely related to the width of the packets. We then com- ment on the possible physical implications, both in classical and quantum physics, and models with extra spatial dimen- sions.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
