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 کاملA Quintessential Axion
The model independent axion of string theory has a decay constant of order of the Planck scale. We explore the properties of this quintessence candidate (quintaxion) in the scheme of hidden sector supergravity breakdown. In models allowing for a reasonable µ term, the hidden sector dynamics may lead to an almost flat potential responsible for the vacuum energy of (0.003 eV) 4. A solution to the...
متن کاملA Theoretical Review of Axion
The standard model SU(3) × SU(2) × U(1) describes the weak and electromagnetic interactions very successfully. The strong interaction part, quantum chromodynamics, is proven to be successful at perturbative level, but the study of nonperturbative effects are not so successful. Because of the lack of a calculational tool of the nonperturbative effects, the frequently used method for the study of...
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...
