Higher curvature gravity at the LHC

We investigate brane-world models in different viable F(R) gravity theories where the Lagrangian is an arbitrary function of the curvature scalar. Deriving the warped metric for this model, resembling Randal-Sundrum (RS)-like solutions, we determine the graviton KK modes. The recent observations at the LHC, which constrain the RS graviton KK modes to a mass range greater than 3 TeV, are incompatible with RS model predictions. It is shown that the models with F(R) gravity in the bulk address the issue, which in turn constrains the F(R) model itself.
