With the establishment and maturation of the experimental programs searching for new
physics with sizeable couplings at the LHC, there is an increasing interest in the broader …

We explore the prospects for direct detection of dark energy by current and upcoming
terrestrial dark matter direct detection experiments. If dark energy is driven by a new light …

We investigate the 5.49 MeV solar axions flux produced in the p (d, He3) a reaction and
analyze the potential to detect it with the forthcoming large underground neutrino oscillation …

The XENON1T collaboration has observed an excess in electronic recoil events below 5
keV over the known background, which could originate from beyond-the-standard-model …

In these notes I try to introduce the reader to the topic of axions: their theoretical motivation
and expected phenomenology, their role in astrophysics and as dark matter candidate, and …

A bstract Axions are well-motivated candidates for dark matter. Recently, much interest has
focused on the detection of photons produced by the resonant conversion of axion dark …

The axion, as a leading dark matter candidate, is the target of many ongoing and proposed
experimental searches based on its coupling to photons. Ultralight axions that couple to …

We revisit the flux of chameleons (light scalar particles which could play a role in the dark
energy phenomenon) produced in the interior of the Sun. Our novel analysis incorporates …

Axions, if realized in nature, can be copiously produced in the early universe via thermal
processes, contributing to the mass-energy density of thermal hot relics. In light of the most …

Many present-day axion searches attempt to probe the mixing of axions and photons, which
occurs in the presence of an external magnetic field. While this process is well understood in …
