From Extended theories of Gravity to Dark Matter

13 May 2016 Choudhury Sayantan Sen Manibrata Sadhukhan Soumya

In this work, we propose different models of extended theories of gravity, which are minimally coupled to the SM fields, to explain the possibility of a dark matter (DM) candidate, without ad-hoc additions to the Standard Model (SM). We modify the gravity sector by allowing quantum corrections motivated from local $f(R)$ gravity, and non-minimally coupled gravity with SM sector and dilaton field... (read more)
