DESI constraints on varying electron mass model and axion-like early dark energy

Baryon acoustic oscillation (BAO) is one of the important standard ruler in cosmology. The results of the latest BAO measurements by Dark Energy Spectroscopic Instrument (DESI) survey has been reported. Cosmology with the varying electron mass model and the early dark energy (EDE) models are regraded as interesting models to resolve the Hubble tension. We present constraints on the varying electron mass model and EDE models by including new DESI data as well as cosmic microwave background by Planck and the conventional BAO data from 6dF, MGS, and DR12 and supernovae light curve data into analysis. Since new DESI BAO data indicates slightly longer sound horizon rdh than the other BAO observations, for the varying electron mass model, the larger H₀ =69. 44 0. 84 km/s/Mpc is indicated.
