We analyze the anisotropic clustering of the Sloan Digital Sky Survey-IV Extended Baryon Oscillation Spectroscopic Survey (eBOSS) Luminous Red Galaxy Data Release 14 (DR14) sample combined with Baryon Oscillation Spectroscopic Survey (BOSS) CMASS sample of galaxies in the redshift range 0.6$

We constrain the logarithmic growth of structure times the amplitude of dark matter density fluctuations, , and the Alcock-Paczynski dilation scales which constraints the angular diameter distance and , where is the sound horizon at the end of the baryon drag epoch and is its value in the fiducial cosmology at an effective redshift . These results are in full agreement with the current -Cold Dark Matter ( -CDM) cosmological model inferred from Planck measurements. This study is the first eBOSS LRG full-shape analysis i.e. including Redshift-Space Distortions (RSD) simultaneously with the Alcock-Paczynski (AP) effect and the Baryon Acoustic Oscillation (BAO) scale.
