Scalar Relics from the Hot Big Bang
Author(s): David Cyncynates and Olivier Simon
In this Letter, we motivate the fact that couplings between a scalar field and the standard model with strengths ${10}^{−6}({m}_{ϕ}/\mathrm{eV}{)}^{−1/4}$ relative to gravity yield the total measured cosmological dark matter abundance over a broad mass range of ${10}^{−12}$ to ${10}^{14}\text{ }\tex… [Phys.
