Search for chameleons with CAST
V. Anastassopoulos, M. Arik, S. Aune +61
In this work we present a search for (solar) chameleons with the CERN Axion Solar Telescope (CAST). This novel experimental technique, in the field of dark energy research, exploit…
CAST constraints on the axion-electron coupling
K. Barth, A. Belov, B. Beltran +53
In non-hadronic axion models, which have a tree-level axion-electron interaction, the Sun produces a strong axion flux by bremsstrahlung, Compton scattering, and axio-recombination…
Solar flares as harbinger of new physics
K. Zioutas, M. Tsagri, Y. Semertzidis +4
This work provides additional evidence on the involvement of exotic particles like axions and/or other WISPs, following recent measurements during the quietest Sun and flaring Sun.…
Signatures for Solar Axions/WISPs
Konstantin Zioutas, Theodoros Vafeiadis, Mary Tsagri +4
Standard solar physics cannot account for the X-ray emission and other puzzles, the most striking example being the solar corona mystery. The corona temperature rise above the non-…
Solar X-rays from Axions: Rest-Mass Dependent Signatures
Konstantin Zioutas, Mary Tsagri, Yannis Semertzidis +4
The spectral shape of solar X-rays is a power law. The more active the Sun is, the less steep the distribution. This behaviour can be explained by axion regeneration to X-rays occu…
Axion Searches with Helioscopes and astrophysical signatures for axion(-like) particles
K. Zioutas, M. Tsagri, Y. Semertzidis +3
The first part reviews the working mechanisms, capabilities and performance of axion helioscopes, including the achieved results so far. The 2nd part is observationally driven. New…
