Big Bang nucleosynthesis in visible and hidden-mirror sectors

Understand

One of the still viable candidates for the dark matter is the so-called mirror matter.

• Its cosmological and astrophysical implications were widely studied in many aspects, pointing out the importance to go further with research and refine the studies.
• In particular, the Big Bang nucleosynthesis provides a strong test for every dark matter candidate, since it is well studied and involves relatively few free parameters.
• The necessity of accurate studies of primordial nucleosynthesis with mirror matter has then emerged.
