A new cosmological scenario is proposed in which a light scalaron of f(R) gravity plays the role dark matter. In this scenario, initially resides at minimum its effective potential while electroweak symmetry unbroken. At beginning crossover, evolving expectation value Higgs field triggers evolution due to interaction between these fields. After oscillating can represent cold Its current energy ...

It is certainly very attractive that two longstanding open questions -the origin of electroweak symmetry breaking -and the nature of the non-baryonic dark matter in the Universeseem to be on the verge of being answered simultaneously and presumably in a unified framework. LHC will give us the opportunity to start scratching the surface of this issue and, if we are lucky enough, to hint more cle...
