This talk presents a unified discussion of glueball dark matter and related composite states in confining dark Yang–Mills sectors. I will first review lattice-inspired effective descriptions of dark confinement and chiral dynamics, and show how the associated phase transitions can lead to potentially observable gravitational-wave signals, especially in fermionic and near-conformal regimes. I...
For feebly interacting massive dark matter particle (FIMP) dark matter, variations in particle mass during cosmological phase transitions can affect the dark matter production mechanism. Meanwhile, reheating, entropy injection, and phase coexistence during phase transitions, especially supercooled phase transitions, also influence the evolution of dark matter abundance to varying degrees. This...
In this talk I will discuss primordial black holes form from slow first-order phase transitions based on the perturbation theory of general relativity.
In this talk, I describe the instabilities of the nontopological strings, and the stability of the topological strings in the class of grand unified theories based on SU(N>5) gauge symmetries. The stability analysis will be based on the 331 model, which is a possible effective theory of such grand unified theories.
