Abstract
We analyse the clustering of cosmic large scale structure using a consistent modied gravity
perturbation theory, accounting for anisotropic effects along and transverse to the line of sight. The
growth factor has a particular scale dependence in f(R) gravity and we fit for the shape parameter
fR0 simultaneously with the distance and the large scale (general relativity) limit of the growth
function. Using more than 690,000 galaxies in the Baryon Oscillation Spectroscopy Survey Data
Release 11, we nd no evidence for extra scale dependence, with the 95% condence upper limit IfR0I < 8 10-4. Future clustering data, such as from the Dark Energy Spectroscopic Instrument,
can use this consistent methodology to impose tighter constraints.
