# Cosmic separation of phases

@inproceedings{itten2011CosmicSO, title={Cosmic separation of phases}, author={Edwax 'd 'itten}, year={2011} }

A first-order QCD phase transition that occurred reversibly in the early universe would lead to a surprisingly rich cosmological scenario. Although observable consequences mould not necessarily survive, it is at least conceivable that the phase transition mould concentrate most of the quark excess ln dcnsc, lnvlslblc qualk nuggcts, prov1d1ng an cxplanat1on for thc dark matter ln terms of QCD effects only. This possibility is viable only if quark matter has energy per baryon 1ess than 938 MeV…

Baryon Number Transfer Could Delay Quark–Hadron Transition in Cosmology

- Physics
- 2016

In the early Universe, strongly interacting matter was a quark–gluon plasma. Both lattice computations and heavy ion collision experiments, however, tell us that, in the absence of chemical…

Remark on the QCD-electroweak phase transition in a supercooled Universe

- Physics

In extensions of the Standard Model with no dimensionful parameters the electroweak phase transition can be delayed to temperatures of order 100 MeV. Then the chiral phase transition of QCD can…

A precision test of the nature of Dark Matter and a probe of the QCD phase transition

- Physics

If dark matter (DM) contains equal numbers of u,d,s quarks, the ratio of DM and ordinary matter densities is shown to follow from the Boltzmann distribution in the Quark Gluon Plasma. For sexaquark…

Trajectory of the cosmic plasma through the quark matter phase diagram

- Physics
- 2016

Experimental studies of the Quark-Gluon Plasma (QGP) focus on two, in practice distinct, regimes: one in which the baryonic chemical potential $\mu_B$ is essentially zero, the other in which it is of…

Proper time regularization and the QCD chiral phase transition

- PhysicsScientific reports
- 2017

It is found that in the chiral limit the whole transition line in the phase diagram is of second order, whereas for finite quark masses a crossover is observed, indicating that the regularization scheme can have a dramatic impact on the study of the QCD phase transition within the NJL model.

Critical point in the QCD phase diagram for extremely strong background magnetic fields

- Physics
- 2015

Lattice simulations have demonstrated that a background (electro)magnetic field reduces the chiral/deconfinement transition temperature of quantum chromodynamics for eB < 1 GeV2. On the level of…

Gravitational waves from first-order phase transitions in Majoron models of neutrino mass

Abstract
We show how the generation of right-handed neutrino masses in Majoron models may be associated with a first-order phase transition and accompanied by the production of a stochastic…

Gravitational waves from neutrino mass genesis

The discovery of gravitational waves opens new opportunities to test BSM physics. In particular, the production of a stochastic background of primordial gravitational waves could provide a signature…
