We measure the luminosity and color dependence and the redshift evolution ofgalaxy clustering in the Sloan Digital Sky Survey-III Baryon OscillationSpectroscopic Survey Ninth Data Release. We focus on the projected two-pointcorrelation function (2PCF) of subsets of its CMASS sample, which includesabout 260,000 galaxies over ~3,300 sq. deg in the redshift range 0.43<z<0.7. Tominimize the selection effect on galaxy clustering, we construct well-definedluminosity and color subsamples by carefully accounting for the CMASS galaxyselection cuts. The 2PCF of the whole CMASS sample, if approximated by apower-law, has a correlation length of r_0=7.93\pm0.06Mpc/h and an index of\gamma=1.85\pm0.01. Clear dependences on galaxy luminosity and color are foundfor the projected 2PCF in all redshift bins, with more luminous and reddergalaxies generally exhibiting stronger clustering and steeper 2PCF. The colordependence is also clearly seen for galaxies within the red sequence,consistent with the behavior of SDSS-II main sample galaxies at lowerredshifts. At a given luminosity (k+e corrected), no significant evolution ofthe projected 2PCFs with redshift is detected for red sequence galaxies. Wealso construct galaxy samples of fixed number density at different redshifts,using redshift-dependent magnitude thresholds. The clustering of these galaxiesin the CMASS redshift range is found to be consistent with that predicted bypassive evolution. Our measurements of the luminosity and color dependence andredshift evolution of galaxy clustering will allow for detailed modeling of therelation between galaxies and dark matter halos and new constraints on galaxyformation and evolution.
