Future constraints on the Hu-Sawicki modified gravity scenario
  We present current and future constraints on the Hu and Sawicki modified
gravity scenario. This model can reproduce a late time accelerated universe and
evade solar system constraints. While current cosmological data still allows
for distinctive deviations from the cosmological constant picture, future
measurements of the growth of structure combined with Supernova Ia luminosity
distance data will greatly improve present constraints.
