Abstract
We show that axion gauge field coupling leads to tachyonic mass generation for the gauge fields when the axion field has an homogeneous and isotropic time dependent (i.e. cosmological) expectation value.In the context of the standard SU(3)*SU(2)*U(1) gauge group, it is possible to eliminate this instability in thermal equilibrium environment provided a finite chemical potential is introduced for B+L. This finite density environment that stabilizes the system, can be generated through B+l violating processes that take place with considerable rate in the standard model at TeV temperatures. In this, way, through a mechanism where CPT is spontaneously violated, baryogenesis can take place in a thermal equilibrium environment at TeV temperatures. (author).
