Are Textures Natural?
Marc Kamionkowski, John March-Russell

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.
