The formation of primary galactic nuclei during phase transitions in the early universe
A new mechanism describing the formation of protogalaxies is proposed, based on the second-order phase transition in the inflation stage and the domain wall formation upon the end of inflation. TheExpand

Gravitational instability of scalar fields and formation of primordial black holes
On considere l'instabilite gravitationnelle d'un etat spatialement uniforme d'un champ scalaire relativiste sur un fond independant du temps. On demontre que l'instabilite est semblable aExpand

Composite dark matter from a model with composite Higgs boson
In a previous paper [Phys. Rev. D77, 065002 (2008)], we showed how the minimal walking technicolor model can provide a composite dark matter candidate, by forming bound states between a -2Expand

Composite dark matter from 4th generation
Hypothesis of heavy stable quark of 4th family can provide a nontrivial solution for cosmological dark matter if baryon asymmetry in 4th family has negative sign and the excess of anti-U quarks withExpand

Possible Origin of Antimatter Regions in the Baryon Dominated Universe
We discuss the evolution of U(1) symmetric scalar field at the inflation epoch with a pseudo Nambu-Goldstone tilt revealing after the end of exponential expansion of the Universe. The U(1) symmetryExpand

Tera-leptons’ shadows over Sinister Universe
The role of Sinister Heavy Fermions in Glashow’s SU(3) × SU(2) × SU(2)′ × U(1) model is to offer in a unique frame relic helium-like products (an ingenious candidate to the dark matter puzzle), aExpand

On the concentration of relic magnetic monopoles in the universe
Abstract The modern concentration of relic 't Hooft-Polyakov monopoles is shown to amount to ∼ 10 −19 cm −3 , being determined by the diffusion annihilation rate at t −5 s. To eliminate theExpand

PHYSICS OF DARK MATTER IN THE LIGHT OF DARK ATOMS
Direct searches for dark matter lead to serious problems for simple models with stable neutral Weakly Interacting Massive Particles (WIMPs) as candidates for dark matter. A possibility is discussedExpand

Probes for Dark Matter Physics
The existence of cosmological dark matter is in the bedrock of the modern cosmology. The dark matter is assumed to be nonbaryonic and to consist of new stable particles. However if composite darkExpand
