Helioseismological constraint on solar axion emission
Stars are powerful sources for low-mass weakly interacting particles. The backreaction of this energy-loss channel on the properties and evolution of stars has been extensively used to constrain nonstandard neutrino couplings and the properties of axions and other hypothetical particles [1]. While the Sun no doubt is the star best known to us, it does not provide the most restrictive limits on ...
متن کاملFirst results from the CERN axion solar telescope.
Hypothetical axionlike particles with a two-photon interaction would be produced in the sun by the Primakoff process. In a laboratory magnetic field ("axion helioscope"), they would be transformed into x-rays with energies of a few keV. Using a decommissioned Large Hadron Collider test magnet, the CERN Axion Solar Telescope ran for about 6 months during 2003. The first results from the analysis...

متن کاملProspects of solar axion searches with crystal detectors
A calculation of the expected signal due to Primakoff coherent conversion of solar axions into photons via Bragg scattering in several crystal detectors is presented. The results are confronted with the experimental sensitivities of present and future experiments concluding that the sensitivity of crystal detectors does not challenge the globular cluster limit on the axion–photon coupling gaγγ ...
متن کاملQCD Axion and Quintessential Axion
The axion solution of the strong CP problem is reviewed together with the other strong CP solutions. We also point out the quintessential axion(quintaxion) whose potential can be extremely flat due to the tiny ratio of the hidden sector quark mass and the intermediate hidden sector scale. The quintaxion candidates are supposed to be the string theory axions, the model independent or the model d...
