Description
We investigate big bang nucleosynthesis (BBN) in Starobinsky gravity model with one additional term RabRab. This model includes various forms of cosmic evolution beyond the standard cosmic evolution based on the Einstein gravity model. Considering this interesting and rich forms of cosmic evolution, we calculate the primordial abundances of 4He, D, 3He, 7Li and 6Li during the BBN period and compare these values with the most recent observation data. We find that the constraint conditions can be most strongly constrained by recent observations of deuterium abundance as well as 4He abundance. In this talk, we introduce the interesting and important results mentioned above and discuss the impliction of these acquired constraints.
