Searching for energetic cosmic axions in a laboratory experiment
Astrophysical sources of energetic gamma rays provide the right conditions for maximal mixing between (pseudo)scalar (axion-like) particles and photons if their coupling is strong enough. This is independent of whether or not the axion interaction is standard at all energies or becomes suppressed in the extreme conditions of the stellar interior. The flux of such particles through the Earth cou...
متن کاملSearching for energetic cosmic axions in a laboratory experiment: testing the PVLAS anomaly
Astrophysical sources of energetic gamma rays provide the right conditions for maximal mixing between (pseudo)scalar (axion-like) particles and photons if their coupling is as strong as suggested by the PVLAS claim. This is independent of whether or not the axion interaction is standard at all energies or becomes suppressed in the extreme conditions of the stellar interior. The flux of such par...
متن کاملA ug 1 99 8 Search for energetic cosmic axions utilizing terrestrial / celestial magnetic fields
Orbiting γ-detectors combined with the magnetic field of the Earth or the Sun can work parasitically as cosmic axion telescopes. The relatively short field lengths allow the axion-to-photon conversion to be coherent for m axion ∼ 10 −4 eV, if the axion kinetic energy is above ∼ 500 keV (Earth's field), or, ∼ 50 MeV (Sun's field), allowing thus to search for axions from e + e − annihilations, fr...
متن کاملThe Energetic Trans-Iron Cosmic-ray Experiment (ENTICE)
The ENTICE experiment is one of two instruments that comprise the ”Orbiting Astrophysical Spectrometer in Space (OASIS)”, which is presently undergoing a NASA ”Astrophysics Strategic Mission Concept Study”. ENTICE is designed to make high precision measurements of the abundances of individual elements from neon through the actinides and, in addition, will search for possible superheavy nuclei i...
متن کاملAxions, Monopoles and Cosmic Strings
We are discussing some aspects of the magnetic monopoles and cosmic strings interactions with axion domain walss and membranes. The monopole moving through an axion domain wall is transformed into a monopole bag the state with a dyon quantum number, but smaller mass. In the case of an axion membrane the passing monopole excites the chiral charged state at the membrane boundary. It will be shown...
