Precision gravity constraints on large dark sectors
Christopher Ewasiuk, Stefano Profumo
General relativity, treated as a low energy effective field theory, predicts quantum corrections to Newtons law of gravitation arising from loops of matter and graviton fields. Whi…

Constraints on the maximal number of dark degrees of freedom from black hole evaporation, cosmic rays, colliders, and supernovae
Christopher Ewasiuk, Stefano Profumo
A dark sector with a very large number of massive degrees of freedom is generically constrained by radiative corrections to Newton's constant. However, there are caveats to this st…
