Big Bang Nucleosynthesis is the most reliable probe of the physical conditions of the early
Universe during the cosmological nucleosynthesis epoch. Therefore, BBN is traditionally used
as a cosmological test of physics beyond the Standard Model. We review several non-standard
BBN models and the obtained cosmological constraints on the baryonic density, the number of
neutrino families, neutrino mixing and neutrino masses, additional particles and inteructions, in
particular on chiral tensor particles coupling.
