Tuesday - Session 1: Big Bang Cosmology and Primordial Nucleosynthesis
- Shigeru Kubono (RIKEN Nishina Center, 2-1 Hirosawa, Wako, Saitama 351-0198, Japan)
In this talk, we will present a mechanism that provides self-interacting dark matter that can explain the small-scale structure problems such as the core cusp and too big to fail issues. We summarize simulations of self-interacting dark matter in models for galaxy formation and evolution. Then, constraints on the self-interacting dark matter with the cosmic microwave background and...
It has been known that there is an outstanding discrepancy between theoretical predictions and astronomical observations of primordial lithium abundances, so called cosmological lithium problem (CLP). From the point of view of nuclear physics, 7Be(n,p)7Li and 7Be(alpha,n)4He are the most important reactions which act to decrease 7Li in Big Bang nucleosynthesis (BBN). There was still lacked...
We will summarize the status of big-bang nucleosynthesis (BBN), which describes the production of the lightest nuclides during the first three minutes of cosmic time. We will emphasize the transformational influence of cosmic microwave background (CMB) experiments culminating today with Planck, which pin down the cosmic baryon density to exquisite precision. Standard BBN combines this with...
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...
