A New Perspective on the Nonextremal Enhancon Solution

TL;DR

This paper explores a nonextremal generalization of the enhancon mechanism, demonstrating that under certain conditions, the shell branch solution remains physically viable and bridges the gap between extremal and nonextremal solutions.

Contribution

It introduces a nonextremal shell branch solution that satisfies energy conditions and connects extremal and nonextremal configurations.

Findings

Nonextremal shell branch does not violate the Weak Energy Condition for small nonextremality.

The shell branch fills the mass gap between extremal and horizon solutions.

The solution extends the enhancon mechanism to nonextremal cases.

Abstract

We discuss the nonextremal generalisation of the enhancon mechanism. We find that the nonextremal shell branch solution does not violate the Weak Energy Condition when the nonextremality parameter is small, in contrast to earlier discussions of this subject. We show that this physical shell branch solution fills the mass gap between the extremal enhancon solution and the nonextremal horizon branch solution.
