Planckian Energy Scattering of D-branes and M(atrix) Theory in Curved Space

TL;DR

This paper explores the formation of black p-branes during high-energy D0-brane collisions, extending previous conjectures about black hole formation at Planckian energies, and examines M(atrix) theory in curved spacetime.

Contribution

It proposes a scenario for black p-brane formation in D-brane collisions and discusses M(atrix) theory and matrix string theory in curved space, highlighting potential quantum coherence violations.

Findings

Black p-branes likely form in Planckian D0-brane collisions.

M(atrix) theory shows signs of quantum coherence violation in curved space.

The collision process can be modeled using colliding plane gravitational waves.

Abstract

We argue that black p-branes will occur in the collision of D0-branes at Planckian energies. This extents the Amati, Ciafaloni and Veneziano and 't Hooft conjecture that black holes occur in the collision of two light particles at Planckian energies. We discuss a possible scenario for such a process by using colliding plane gravitational waves. D-branes in the presence of black holes are discussed. M(atrix) theory and matrix string in curved space are considered. A violation of quantum coherence in M(atrix) theory is noticed.
