The Origin of Mass and the Particle Nature of Dark Matter

2021
This thesis comprises six papers written during my Ph.D studies and also includes one relevant paper written before the Ph.D. In all these studies, we construct and consider “(Partially) Composite Higgs” ((P)CH) models, a variant of dynamical electroweak (EW) symmetry breaking models that provide a “pseudo-Nambu-Goldstone Boson” (pNGB) composite Higgs ...

Dark Particles as a Possible Unified Nature of Dark Energy and Dark Matter

В работе выдвинута гипотеза, объединяющая тёмную энергию и тёмную материю как два проявления одной популяции самореплицирующихся тёмных частиц: репликативное давление в разреженном пространстве даёт эффект тёмной энергии и закон Хаббла, а накопление тех же частиц у галактик — эффект тёмной материи и гало. Унификация отличает модель от ΛCDM.

The Non-Particle Nature of Dark Matter — Freezing of Type-B Geometric Defects

Dark matter constitutes about 85% of the matter in the universe, yet its nature remains unknown. The standard weakly interacting massive particle (WIMP) and axion models face severe challenges from the persistent null results of direct detection experiments.

Phenomenological Investigations of Dark Matter’s Particle Nature with the Fermi Galactic Center GeV Excess and gaia wide binaries

Astrophysical systems provide us with information regarding dark matter's particle nature that is inaccessible to Earth-based experiments. In this thesis, we study two such astrophysical systems: an unexplained source of GeV-scale gamma-rays known as the Fermi Galactic Center Excess (GCE) and wide binary star systems.
