Fermion dispersion in axion medium
arXiv:0812.0516 · doi:10.1142/S0217751X08041608
Abstract
The interaction of a fermion with the dense axion medium is investigated for the purpose of finding an axion medium effect on the fermion dispersion. It is shown that axion medium influence on the fermion dispersion under astrophysical conditions is negligible small if the correct Lagrangian of the axion-fermion interaction is used.
