In this study, we investigated a model of massvarying neutrinos in which the mass depends on the value of a scalar field representing the dark energy component. The originality of our work lies in the choice of the quintessence parametrization, which limits the number of free parameters with respect to other approaches such as the CPL parametrization or arbitrary choices of scalar field potentials.
