Light scalaron as dark matter
A new cosmological scenario is proposed in which a light scalaron of f(R) gravity plays the role of dark matter. In this scenario, the scalaron initially resides at the minimum of its effective potential while the electroweak symmetry is unbroken. At the beginning of the electroweak crossover, the e...
