Axions from wall decay

چکیده

We discuss the decay of axion walls bounded by strings and present numerical simulations of the decay process. In these simulations, the decay happens immediately, in a time scale of order the light travel time, and the average energy of the radiated axions is 〈ωa〉 ≃ 7ma for va/ma ≃ 500. 〈ωa〉 is found to increase approximately linearly with ln(va/ma). Extrapolation of this behaviour yields 〈ωa〉 ≃ 60ma in axion models of interest.

Studies of the motion and decay of axion walls bounded by strings. Abstract We discuss the appearance at the QCD phase transition, and the subsequent decay, of axion walls bounded by strings in N = 1 axion models. We argue on intuitive grounds that the main decay mechanism is into barely relativistic axions. We present numerical simulations of the decay process. In these simulations, the decay ...

Axions as hot and cold dark matter

The presence of a hot dark matter component has been hinted at 3σ by a combination of the results from different cosmological observations. We examine a possibility that pseudo Nambu-Goldstone bosons account for both hot and cold dark matter components. We show that the QCD axions can do the job for the axion decay constant fa . O ( 1010 ) GeV, if they are produced by the saxion decay and the d...

The cold axion populations

We give a systematic discussion of the contributions to the cosmological energy density in axions from vacuum realignment, string decay and wall decay. We call these the cold axion populations because their kinetic energy per particle is at all times much less than the ambient temperature. In case there is no inflation after the Peccei-Quinn phase transition, the value of the axion mass for whi...

Searching for axions and ALPs from string theory

We review searches for closed string axions and axion-like particles (ALPs) in IIB string flux compactifications. For natural values of the background fluxes and TeV scale gravitino mass, the moduli stabilisation mechanism of the LARGE Volume Scenario predicts the existence of a QCD axion candidate with intermediate scale decay constant, fa ∼ 10 9÷12 GeV, associated with the small cycles wrappe...

Axions from String Decay

We have studied numerically the evolution and decay of axion strings. These global defects decay mainly by axion emission and thus contribute to the cosmological axion energy density. The relative importance of this source relative to misalignment production of axions depends on the spectrum. Radiation spectra for various string loop configurations are presented. They support the contention tha...
