Constraining the Hubble constant and extensions of the standard model
Keywords:Cosmology, beyond the standard model, Hubble tension, varying fundamental constants.
Abstract:Recent findings present substantial challenges to the $\Lambda$CDM model. Discrepancies in the Hubble constant
measurement and other quandaries confronting standard cosmology imply deficiencies in its comprehension, hinting at the
potential necessity for new physics. Our investigation is centered on the observational evaluation of extensions to the standard
model. Furthermore, we must constraint cosmological parameters.
