The chirality imbalance in QCD is spontaneously induced by a repulsive axial-vector interaction from the instanton anti-instanton pairing at high temperature above the chiral phase transition, and vanishes at low temperature. Phase transition of the chirality imbalance is always a first-order one in the early universe with P and CP violation. The spectra of gravitational waves and the formation of the primordial black holes from this first-order phase transition is investigated in this work, and…

Chiral magnetic effect in heavy ion collisions and beyond

Chirality is a ubiquitous concept in modern science, from particle physics to biology. In quantum physics, chirality of fermions is linked to topology of gauge fields by the chiral anomaly. While the

Chiral phase transition and instanton-anti-instanton molecules.

The degree of polarization of the molecules as a function of the temperature is calculated and it is shown that the resulting [ital T] dependence of the fermion determinant drives the chiral phase transition.

Primordial black holes with an accurate QCD equation of state

Making use of definitive new lattice computations of the Standard Model thermodynamics during the quantum chromodynamic (QCD) phase transition, we calculate the enhancement in the mass distribution

The order of the quantum chromodynamics transition predicted by the standard model of particle physics

Finite-size scaling analysis shows that the finite-temperature QCD transition in the hot early Universe was not a real phase transition, but an analytic crossover (involving a rapid change, as opposed to a jump, as the temperature varied).

Search for the Chiral Magnetic Effect in Au+Au collisions at $\sqrt{s_{_{\rm{NN}}}}=27$ GeV with the STAR forward Event Plane Detectors

A decisive experimental test of the Chiral Magnetic Effect (CME) is considered one of the major scientific goals at the Relativistic Heavy-Ion Collider (RHIC) towards understanding the nontrivial

Gravitational radiation from first-order phase transitions.

This work considers the stochastic background of gravity waves produced by first-order cosmological phase transitions from two types of sources: colliding bubbles and hydrodynamic turbulence and finds that the characteristic amplitude of the gravity wavesproduced is comparable to that from bubble collisions.

We calculate the gravitational-wave spectra produced by the electroweak phase transition with TeV-scale Beyond-Standard-Model physics in the early universe. Our study captures the effect of quantum

Primordial Black Hole Formation during the QCD Epoch

We consider the formation of horizon-size primordial black holes (PBH{close_quote}s) from pre-existing density fluctuations during cosmic phase transitions. It is pointed out that the formation of

We survey systematically the general parametrisations of particle-physics models for a first-order phase transition in the early universe, including models with polynomial potentials both with and
