Most embeddings of the Standard Model into a more unified theory, in particular those based on supergravity or superstrings, predict the existence of a hidden sector of particles that have only very
Exploring the Role of Axions and Other WISPs in the Dark Universe
Axions and other very weakly interacting slim particles (WISPs) may be non-thermally produced in the early universe and survive as constituents of the dark universe. We describe their theoretical
An improved limit on the axion–photon coupling from the CAST experiment
We have searched for solar axions or similar particles that couple to two photons by using the CERN Axion Solar Telescope (CAST) set-up with improved conditions in all detectors. From the absence of

We evaluate the efficiency of axion production from spatially random initial conditions in the axion field, so a network of axionic strings is present. For the first time, we perform numerical

The laboratory, astrophysical and cosmological constraints on $\phi$ are examined, it is generalized to possess $SU(2) \times U(1)$ gauge invariance, and the phenomenological implications are analyzed.
Experimental targets for photon couplings of the QCD axion

A bstractThe QCD axion’s coupling to photons is often assumed to lie in a narrow band as a function of the axion mass. We demonstrate that several simple mechanisms, in addition to the photophilic

Abstract By coupling axions strongly to a hidden sector, the energy density in coherent axions may be converted to radiative degrees of freedom, alleviating the “axion energy crisis”. The strong
