Abstract
We investigate the tension in a range of extended model frameworks beyond the standard CDM without the data from cosmic microwave background (CMB). Specifically, we adopt the data from baryon acoustic oscillation, big bang nucleosynthesis and type Ia supernovae as indirect measurements of to study the tension. We show that the estimated value of from indirect measurements is overall lower than that from direct local ones regardless of the data sets and a range of extended models to be analyzed, which indicates that, although the significance of the tension varies depending on models, the tension persists in a broad framework beyond the standard CDM model even without CMB data.
