Six flavor quark matter

A bstractMacroscopic nuggets of quark matter were proposed several decades ago as a candidate for dark matter. The formation of these objects in the early universe requires the QCD phase transition to be first order — a requirement that is not satisfied in the Standard Model where lattice simulations reveal a continuous crossover instead. In this article we point out that new physics may supercool the electroweak phase transition to below the QCD scale, and the QCD phase transition with six… 

Dark quark nuggets

"Dark quark nuggets", a lump of dark quark matter, can be produced in the early universe for a wide range of confining gauge theories and serve as a macroscopic dark matter candidate. The two

Updated cosmological constraints on Macroscopic Dark Matter

We revise the cosmological phenomenology of Macroscopic Dark Matter (MDM) candidates, also commonly dubbed as Macros. A possible signature of MDM is the capture of baryons from the cosmological

Fermi-ball dark matter from a first-order phase transition

We propose a novel dark matter (DM) scenario based on a first-order phase transition in the early universe. If dark fermions acquire a huge mass gap between true and false vacua, they can barely

Super-cool Dark Matter

A bstractIn dimension-less theories of dynamical generation of the weak scale, the Universe can undergo a period of low-scale inflation during which all particles are massless and undergo

Tests of Dark MACHOs: lensing, accretion, and glow

Dark matter could take the form of dark massive compact halo objects (dMACHOs); i.e., composite objects that are made up of dark-sector elementary particles, that could have a macroscopic mass from

Dibaryons cannot be the dark matter

The hypothetical $SU(3)$ flavor-singlet dibaryon state $S$ with strangeness $-2$ has been discussed as a dark-matter candidate capable of explaining the curious 5-to-1 ratio of the mass density of

The supercooled universe

A bstractStrongly-coupled theories at the TeV can naturally drive a long period of supercooling in the early universe. Trapped into the deconfined phase, the universe could inflate and cool down till

Review of cosmic phase transitions: their significance and experimental signatures

Different types of phase transitions that can appear in cosmic history, and their applications and experimental signatures in particular in the context of exciting gravitational waves, are reviewed, which could be potentially be constrained by LIGO/VIRGO, Kagra, LISA, and Decigo.

Baryogenesis and Dark Matter in Multiple Hidden Sectors

: We explore a mechanism for producing the baryon asymmetry and dark matter in models with multiple hidden sectors that are Standard Model-like but with varying Higgs mass parameters. If the field

Gravitational waves from patterns of electroweak symmetry breaking: an effective perspective

The future space-borne gravitational wave (GW) detectors would provide a promising probe for the new physics beyond the standard model that admits the first-order phase transitions. The predictions



Axion field and the quark nugget's formation at the QCD phase transition

We study a testable dark-matter (DM) model outside of the standard weakly interacting massive particle paradigm in which the observed ratio Ωdark≃Ωvisible for visible and dark-matter densities finds

Physics and astrophysics of strange quark matter

3-flavor quark matter (strange quark matter; SQM) can be stable or metastable for a wide range of strong interaction parameters. If so, SQM can play an important role in cosmology, neutron stars,

Baryon asymmetry, dark matter, and quantum chromodynamics

We propose a novel scenario to explain the observed cosmological asymmetry between matter and antimatter, based on nonperturbative QCD physics. This scenario relies on a mechanism of separation of

QCD-Electroweak First-Order Phase Transition in a Supercooled Universe.

It is shown that, depending on the model parameters, a dramatically different scenario may happen: A first-order, six massless quark QCD phase transition occurs first, which then triggers the electroweak symmetry breaking, which potentially rich in cosmological consequences.

Dark matter in the standard model?

We critically reexamine two possible Dark Matter candidate within the Standard Model. First, we consider the $uuddss$ exa-quark. Its QCD binding energy could be large enough to make it (quasi)

`Nonbaryonic' dark matter as baryonic colour superconductor

We discuss a novel cold dark matter candidate which is formed from the ordinary quarks during the QCD phase transition when the axion domain wall undergoes an unchecked collapse due to the tension in

QCD-induced electroweak phase transition

A bstractPhase transitions associated with nearly conformal dynamics are known to lead to significant supercooling. A notorious example is the phase transition in Randall-Sundrum models or their CFT

Light flavor-singlet scalars and walking signals in Nf=8 QCD on the lattice

Based on the highly improved staggered quark action, we perform lattice simulations of Nf=8 QCD and confirm our previous observations, both of a flavor-singlet scalar meson (denoted as σ) as light as

Macro Dark Matter

Dark matter is a vital component of the current best model of our Universe, Λcold dark matter. There are leading candidates for what the dark matter could be (e.g. weakly interacting massive

Cosmic separation of phases

A first-order QCD phase transition that occurred reversibly in the early universe would lead to a surprisingly rich cosmological scenario. Although observable consequences would not necessarily
