We consider a dataset consisting of 17 data points extending up to redshift z=1.52 and corrected for the Alcock-Paczynski effect. Thus, calculating the evolution of the growth factor in a wCDM cosmology, we find that the tension for the best fit parameters w, Omega m and sigma 8 with respect to the Planck 2018 Lambda CDM parameters is below 2 sigma in all the marginalized confidence regions. eng https://creativecommons.org/licenses/by/3.0/es/ open access Atribución 3.0 España On the tension between growth rate and CMB data journal article
