We present a joint analysis of the Planck cosmic microwave background (CMB)and Baryon Oscillation Spectroscopic Survey (BOSS) final data releases. A keynovelty of our study is the use of a new full-shape (FS) likelihood for theredshift-space galaxy power spectrum of the BOSS data, based on an improvedperturbation theory template. We show that the addition of the redshift spacegalaxy clustering measurements breaks degeneracies present in the CMB dataalone and tightens constraints on cosmological parameters. Assuming the minimal$\Lambda$CDM cosmology with massive neutrinos, we find the followinglate-Universe parameters: the Hubble constant \mbox{$H_0=67.95^{+0.66}_{-0.52}$km s$^{-1}$Mpc$^{-1}$}, the matter density fraction\mbox{$\Omega_m=0.3079^{+0.0065}_{-0.0085}\,$}, the mass fluctuation amplitude\mbox{$\sigma_8=0.8087_{-0.0072}^{+0.012}\,$}, and an upper limit on the sum ofneutrino masses \mbox{$M_{\text{tot}} <0.16\,$ eV} ($95\%$ CL).This can becontrasted with the Planck-only measurements: \mbox{$H_0=67.14_{-0.72}^{+1.3}$}km s$^{-1}$Mpc$^{-1}$, $\Omega_m=0.3188^{+0.0091}_{-0.016}\,$,\mbox{$\sigma_8=0.8053_{-0.0091}^{+0.019}\,$}, and \mbox{$M_{\text{tot}}<0.26\,$ eV} ($95\%$ CL). Our bound on the sum of neutrino masses relaxes oncethe hierarchy-dependent priors from the oscillation experiments are imposed.The addition of the new FS likelihood also constrains the effective number ofextra relativistic degrees of freedom, \mbox{$N_{\text{eff}}=2.88\pm 0.17$}.Our study shows that the current FS and the pure baryon acoustic oscillationdata add a similar amount of information in combination with the Plancklikelihood. We argue that this is just a coincidence given the BOSS volume andefficiency of the current reconstruction algorithms.In the era of futuresurveys FS will play a dominant role in cosmological parameter measurements.
