Tom Bouley (Oregon) “Constraining Ultralight Scalar Dark Matter with Quadratic Couplings from Big Bang Nucleosynthesis”
–
In this talk I present recent work, deriving constraints on ultralight dark matter form Big Bang Nucleosynthesis. The work shows that the presence of ultralight dark matter can modify the effective values of fundamental constants during Big Bang Nucleosynthesis, affecting the predicted abundances of the primordial elements such as Helium-4. The dark matter evolution is influenced by interactions with the … Read More
