Description

We investigate whether there are evidences for the existence of a new tension on the matter density parameter, independent or in relation with the Hubble or the matter fluctuation parameter tension, and that using a combination of multiple probes in a model independent approach where we relax most of the calibration parameters related to the aforementioned discrepancies.
