Colliding fields in two-dimensional dilaton gravity background

TL;DR

This paper investigates field collisions in a 2D dilaton gravity background, revealing that ghost field collisions can create wormholes that collapse into black holes when ghosts are removed.

Contribution

It introduces the phenomenon of ghost field collisions forming wormholes in 2D dilaton gravity, a novel insight into field interactions and spacetime structures.

Findings

Ghost field collisions produce particle-like wormholes.

Removing ghosts causes wormholes to collapse into black holes.

The study highlights the role of ghost fields in spacetime topology.

Abstract

In the 1+1-dimensional dilatonic background of Callan et al. \cite{Callan1992}, we collide fields. Real and ghost fields are considered separately. The colliding ghost fields in the lineland creates particle-like wormholes. These structures, however, collapse to a black hole whenever the supporting ghosts are removed.
