TL;DR
This paper explores the theoretical possibility of stable dark quark domains filled with strongly correlated quark matter, which would appear dark to external observers, using the Generalised Nambu-Jona-Lasinio model.
Contribution
It introduces the concept of dark quark domains and discusses their formation and properties within a specific theoretical framework.
Findings
Dark quark domains could exist in the Universe.
Such domains would be invisible or 'dark' to external observers.
The Generalised Nambu-Jona-Lasinio model supports their theoretical plausibility.
Abstract
Formation of stable domains filled with strongly correlated coherent quark matter is discussed in general terms and is exemplified further in the framework of the Generalised Nambu-Jona-Lasinio model. It is argued that such domains, if exist in the Universe, appear dark to an external observer.
