Titre |
Macroscopic Dark Matter from a dark confining phase transition |
|
Résumé |
First order phase transitions can leave relic pockets of false vacua and their
particles, that manifest as macroscopic Dark Matter. I present one predictive
model: a gauge theory with a dark quark relic heavier than the confinement scale.
During the first order phase transition to confinement, dark quarks remain in the
false vacuum and get compressed, forming Fermi balls that can undergo
gravitational collapse to stable dark dwarfs (gravitational bound states analogous
to white dwarfs) near the Chandrasekhar limit, or primordial black holes. Dark
Matter manifests as a macroscopic object made of dark particles. |
