KalbRamond axion production in anisotropic string cosmologies
Abstract
We compute the energy spectra for massless KalbRamond axions in fourdimensional anisotropic string cosmology models. We show that, when integrated over directions, the fourdimensional anisotropic model leads to infrared divergent spectra similar to the one found in the isotropic case.
