Hubble constant in the axi-Higgs universe
The Λ-cold-dark-matter (ΛCDM) model provides an excellent fit to the cosmic microwave background (CMB) data. However, a statistically significant tension emerges when its determination of the Hubble constant H_{0} is compared to the local distance-redshift measurements. The axi-Higgs model, which co...
