Are Textures Natural?

TL;DR

The paper argues that textures, due to symmetry-violating operators from Planck-scale physics, are too short-lived to be useful for large-scale structure formation.

Contribution

It highlights the impact of Planck-scale physics on the longevity of textures, challenging their role in cosmological structure formation.

Findings

Textures are generally too short-lived for structure formation

Global symmetry violations affect texture stability

Planck-scale operators induce decay in textures

Abstract

We make the simple observation that, because of global symmetry violating higher-dimension operators expected to be induced by Planck-scale physics, textures are generically much too short-lived to be of use for large-scale structure formation.
