Upper limits on dark energy-dark matter interaction from DESI DR2 in a field-theoretic analysis
Amin Aboubrahim, Pran Nath
One of the important issues both in particle physics and cosmology relates to whether dark energy is a cosmological constant , or is dynamical in nature such as quintessence. In…
Interacting ultralight dark matter and dark energy and fits to cosmological data in a field theory approach
Amin Aboubrahim, Pran Nath
The description of dark matter as a pressure-less fluid and of dark energy as a cosmological constant, both minimally coupled to gravity, constitutes the basis of the concordance $…
Cosmologically Consistent Analysis of Gravitational Waves from hidden sectors
Wan-Zhe Feng, Jinzheng Li, Pran Nath
Production of gravitational waves in the early universe is discussed in a cosmologically consistent analysis within a first order phase transition involving a hidden sector feebly…
Particle physics and cosmology intertwined
Pran Nath
While the standard model accurately describes data at the electroweak scale without inclusion of gravity, beyond the standard model physics is increasingly intertwined with gravita…
Hot vs cold hidden sectors and their effects on thermal relics
Jinzheng Li, Pran Nath
A variety of possibilities exist for dark matter aside from WIMPS, such as hidden sector dark matter. We discuss synchronous thermal evolution of visible and hidden sectors and sho…
