Vacuum pressure, dark energy and dark matter

TL;DR

This paper explores the relationship between vacuum pressure, dark energy, and dark matter, proposing that additional fundamental particles could unify these concepts and influence quantum vacuum properties.

Contribution

It suggests that extra bosonic particles are necessary for positive vacuum energy density and links dark matter to vacuum pressure and dark energy.

Findings

Additional bosonic particles may explain vacuum energy sign

Dark matter particles could be related to vacuum pressure

Unified view of dark energy, dark matter, and vacuum pressure

Abstract

It has been argued that the correct, i.e. positive, sign of quantum vacuum energy density, or more properly, negative sign of quantum vacuum pressure, requires not a very large number, e.g. ~100, of additional, undiscovered fundamental bosonic particle species, absent in the standard model. Interpretation of the new particle species in terms of dark matter ones permits to qualitatively, and even quantitatively, connect all the three concepts given in the title.
