Constraints on the exponential $f (R)$ model from latest Hubble parameter measurements

Yun Chen, Chao-Qiang Geng, Chung-Chi Lee +2

We investigate the viable exponential $f (R)$ gravity in the metric formalism with $f (R) = - β R_{s} (1 - e^{- R / R_{s}})$ . The latest sample of the Hubble parameter measurements with 23 data p…
