N2 - We present the clustering measurements of quasars in configuration spacebased on the Data Release 14 (DR14) of the Sloan Digital Sky Survey IVextended Baryon Oscillation Spectroscopic Survey. This dataset includes148,659 quasars spread over the redshift range 0.8 ≤ z ≤ 2.2 andspanning 2112.9 square degrees. We use the Convolution LagrangianPerturbation Theory (CLPT) approach with a Gaussian Streaming (GS) modelfor the redshift space distortions of the correlation function anddemonstrate its applicability for dark matter halos hosting eBOSS quasartracers. At the effective redshift zeff = 1.52, we measurethe linear growth rate of structurefσ8(zeff) = 0.426 ± 0.077, theexpansion rate H(z_eff)=159^{+12}_{-13}(rs^fid/r_s)km.s^{-1}.Mpc^{-1}, and theangular diameter distance DA(z_eff)=1850^{+90}_{-115}(r_s/rs^fid)Mpc, where rs is the sound horizon atthe end of the baryon drag epoch and rs^fid is its value inthe fiducial cosmology. The quoted uncertainties include both systematicand statistical contributions. The results on the evolution of distancesare consistent with the predictions of flat Λ-Cold Dark Matter(Λ-CDM) cosmology with Planck parameters, and the measurement offσ8 extends the validity of General Relativity (GR) tohigher redshifts(z > 1) This paper is released with companion papersusing the same sample. The results on the cosmological parameters of thestudies are found to be in very good agreement, providing clear evidenceof the complementarity and of the robustness of the first full-shapeclustering measurements with the eBOSS DR14 quasar sample.
