Can Dark Matter be an artifact of extended theories of gravity?

Understand

In this article, we propose different background models of extended theories of gravity, which are minimally coupled to the SM fields, to explain the possibility of genesis of dark matter without affecting the SM particle sector.

• We modify the gravity sector by allowing quantum corrections motivated from (1) local $f(R)$ gravity and (2) non-minimally coupled gravity with SM sector and dilaton field.
• Next we apply conformal transformation on the metric to transform the action back to the Einstein frame.
• We also show that an effective theory constructed from these extended theories of gravity and SM sector looks exactly the same.
