Running vacuum versus the $\mathrm{\Lambda }$CDM

It is well-known that a constant $\mathrm{\Lambda }$-term is a traditional building block of the concordance $\mathrm{\Lambda }$CDM model. We show that this assumption is not necessarily the optimal one from the phenomenological point of view. The class of running vacuum models, with a possible running of the gravitational coupling G, are capable to fit the overall cosmological data SNIa+BAO+H(z)+LSS+BBN+CMB better than the $\mathrm{\Lambda }$CDM, namely at a level of $\sim 3\sigma$ and with Akaike and Bayesian information criteria supporting a strong level of statistical evidence on this fact. Here we report on the results of such analysis.
