Description
This record contains data used in the paper "Thermal axion production at hard and soft momenta" (2404.06113). Please refer to this paper for details on the methods used and their numerical implementations.
We used the values of the strong coupling constant and heavy quark thermal masses from 1911.09123. We thank Mikko Laine for provinding us with this data.
Values for the Standard Model equation of state were taken from the dataset available here, relating to 1503.04935.
Update September 2026 : Fixed error in computation of the entropy density at CMB temperatures. Only $\Delta N_{\rm eff}$ results are affected (deltaneff_data*.dat file).
Table of contents (English)
The tarball contains the following files:
- "prodrate.dat": Axion production rate on a temperature - comoving momentum grid for the 3 production rate computation schemes
- "phenomenology_fPQ_all.dat": (Normalized) axion number density and energy density for various tempeatures and values of the axion scale, obtained by solving the Boltzmann equation using the momentum-averaged approximation
- "phenomenology_fPQ_all_dep.dat": Same as above but using the momentum-dependent method to solve the Boltzmann equation
- "deltaneff_data_v2.dat": Contribution to the effective number of neutrinos for various values of the axion scale
