                         parameters combining 15 measurements of the transversal BAO scale 
                         (obtained free of any fiducial cosmology) with Planck-CMB data to 
                         explore the parametric space of some cosmological models. We 
                         investigate how much Planck + transversal BAO data can constraint 
                         the minimum Lambda cold dark matter (Lambda CDM) model, and 
                         extensions, including neutrinos mass scale M-nu, and the 
                         possibility for a dynamical dark energy (DE) scenario. Assuming 
                         the Lambda CDM cosmology, we find H-0 = 69.23 +/- 0.50 km s(-1) 
                         Mpc(-1), M-nu < 0.11 eV, and r(drag) = 147.59 +/- 0.26 Mpc (the 
                         sound horizon at drag epoch) from Planck + transversal BAO data. 
                         When assuming a dynamical DE cosmology, we find that the inclusion 
                         of the BAO data can indeed break the degeneracy of the DE free 
                         parameters, improving the constraints on the full parameter space 
                         significantly. We note that the model is compatible with local 
                         measurements of H-0 and there is no tension on H-0 estimates in 
                         this dynamical DE context. Also, we discuss constraints and 
                         consequences from a joint analysis with the local H-0 measurement 
                         from SH0ES. Finally, we perform a model-independent analysis for 
                         the deceleration parameter, q(z), using only information from 
                         transversal BAO data.",
