Revisiting Metastable Dark Energy and Tensions in the Estimation of Cosmological Parameters

We investigate constraints on some key cosmological parameters by confronting metastable dark energy (DE) models with different combinations of the most recent cosmological observations. Along with the standard ΛCDM model, two phenomenological metastable DE models are considered: (i) DE decays expon...
