QCD 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...
متن کاملAxion-photon couplings in invisible axion models.
We reexamine the axion-photon couplings in various invisible axion models motivated by the recent proposal of using optical interferometry at the ASST facility in the SSCL to search for axion. We illustrate that the assignment of U(1)PQ charges for the fermion fields plays an important role in determining the couplings. Several simple non-minimal invisible axion models with suppressed and enhan...
متن کاملAxion Cosmology
The Strong CP Problem and its resolution through the existence of an axion are briefly reviewed. The combined constraints from accelerator searches, the evolution of red giants and the duration of the SN 1987a neutrino pulse require the axion mass ma to be less than 3 · 10−3 eV. On the other hand, the requirement that the axion does not overclose the universe implies a lower bound on ma of orde...
متن کاملAxion Searches
The strong CP problem and its resolution through the existence of an axion are briefly reviewed. The constraints on the axion from accelerator searches, from the evolution of red giants and from supernova SN1987a combine to require ma < 3 · 10 −3 eV, where ma is the axion mass. On the other hand, the constraint that axions do not overclose the universe implies ma > ∼ 10 eV. If ma ∼ 10 −5 eV, ax...
متن کاملFuture axion searches with the International Axion Observatory (IAXO)
The International Axion Observatory (IAXO) is a new generation axion helioscope aiming at a sensitivity to the axion-photon coupling of gaγ & few×10−12 GeV−1, i.e. 1-1.5 orders of magnitude beyond the one achieved by CAST, currently the most sensitive axion helioscope. The main elements of IAXO are an increased magnetic field volume together with extensive use of x-ray focusing optics and low b...
