Symmetries and selection rules: optimising axion haloscopes for Gravitational Wave searches

Journal of High Energy Physics
In the presence of electromagnetic fields, both axions and gravitational waves (GWs) induce oscillating magnetic fields: a potentially detectable fingerprint of their presence. We demonstrate that the response is largely dictated by the symmetries of the

Matter and antimatter in the universe

New Journal of Physics, 2012
We review observational evidence for a matter–antimatter asymmetry in the early universe, which leads to the remnant matter density we observe today.

Particle astrophysics [PDF]

The following scientific areas are reviewed: (1) cosmology and particle physics (particle physics and the early universe, dark matter, and other relics); (2) stellar physics and particles (solar neutrinos, supernovae, and unconventional particle physics);

Unified origin of curvature perturbation and baryon asymmetry of the universe

Journal of High Energy Physics
We propose a unified framework that describes both the curvaton mechanism for generating primordial density fluctuations and the Affleck-Dine (AD) mechanism for baryogenesis.

Higgs vacuum stability and inflationary dynamics after BICEP2 and PLANCK dust polarisation data

, 2014
If the recent detection of $B-$mode polarization of the Cosmic Microwave Background by BICEP2 observations, withstand the test of time after the release of recent PLANCK dust polarisation data, then it would surprisingly put the inflationary scale near ...

Gauguin's questions in particle physics: Where are we coming from? What are we? Where are we going?

, 2007
Within particle physics itself, Gauguin's questions may be interpreted as: P1 - What is the status of the Standard Model? P2 - What physics may lie beyond the Standard Model? P3 - What is the `Theory of Everything'?

Freezing-in cannibal dark sectors

Journal of High Energy Physics
Self-Interacting Dark Matter models can successfully explain dark matter (DM) production through interactions confined within the dark sector. However, they often lack measurable experimental signals due to their secluded nature.

Physics of Primordial Universe

, 2003
The physical basis of the modern cosmological inflationary models with baryosynthesis and nonbaryonic dark matter and energy implies such predictions of particle theory, that, in turn, apply to cosmology for their test. It makes physics of early Universe

Freezing-in cannibals with low-reheating temperature

Journal of High Energy Physics
The freeze-in mechanism provides a compelling framework for dark matter (DM) production, particularly suited to scenarios involving feeble interactions with the Standard Model (SM).
