The linear growth of structure in Projected Massive Gravity
  In the present paper, we investigate the linear growth of matter fluctuations
based on a concrete model of the projected massive gravity, which is free of
the Boulware-Deser ghost and preserves the global Lorentz symmetry. We found
that at subhorizon scales, the modification to the linear growth is strongly
suppressed even without nonlinear screening of an additional force. In
addition, we obtain observational constraints from distance and redshift space
distortion measurements and find that there is a parameter region that is
consistent both observationally and theoretically.
