The effects of the U${}_{\text{Y}}$(1) Chern-Simons term and its baryonic contribution on matter asymmetries and hypermagnetic fields

S. Rostam Zadeh, S. S. Gousheh

In this paper, we study the significance of the U${}_{\text{Y}}$(1) Chern-Simons term in general, and its baryonic contribution in particular, for the evolution of the matter asymmet…
