Axion I
- Maeve Madigan (Heidelberg University)
The electron-ion collider (EIC), a new powerful high-luminosity
facility, will be able to open up new windows of opportunities to explore new physics. In this
paper, we study the potential of the EIC to probe the coupling between axion-like particles
(ALPs) and photons in coherent scattering, where the ion stays intact, resulting in a cross section
enhancement proportional to the square of...
Although a direct search for the QCD axion at colliders may not be viable due to the feebleness of the axion couplings to the standard model, collider experiments may be sensitive to signatures of the axino, the supersymmetric partner of the axion. The couplings of the axion and axino are related to the axion decay constant $f_{a}$, and so collider searches for the axino may be a way to set...
We consider the general class of theories in which there is a new ultralight scalar field that mediates an equivalence principle violating, long-range force. In such a framework, the Sun and Earth act as sources of the scalar field, leading to potentially observable location-dependent effects on atomic and nuclear spectra. We determine the sensitivity of current and next-generation atomic and...
The QCD axion is a well-motivated extension of the Standard Model which dynamically relaxes away strong CP violation. However, to date most searches for the axion have instead focused on its model-dependent coupling to photons. I will present a new idea for axion detection that directly targets its defining coupling to gluons, by resonantly amplifying the oscillating currents from time-varying...
Ultralight bosonic particles, including axionlike particles and kinetically mixed dark photons, can be promising dark matter candidates. It was recently shown that the Earth can act as a transducer for ultralight dark matter detection, by converting the dark matter into an oscillating monochromatic magnetic field signal across the Earth's surface. This occurs because the ground and...
