Description
Summary:We discuss an extended model with chiral tensor particles (CTP) in the Universe. Their direct influence on the Universe dynamics and their characteristic interactions in the hot Universe plasma, i.e. their creation, scattering annihilation and decay are briefly reviewed. We provide cosmological constraints on the tensor particles coupling, based on the possible interactions of these particles with right-handed neutrinos and their influence on the Big Bang Nucleosynthesis.
