In the past few years, $f(Q)$ theories have drawn a lot of research attention in replacing Einstein's theory of gravity successfully.
- The current study examines the novel cosmological possibilities emerging from two specific classes of $f(Q)$ models using the parametrization form of the equation of state (EoS) parameter as $\omega \left( z\right) =-\frac{1}{1+3\beta \left( 1+z\right) ^{3}}$, which displays quintessence behavior with the evolution of the Universe.
- We do statistical analyses using the Markov chain Monte Carlo (MCMC) method and background datasets like Type Ia Supernovae (SNe Ia) luminosities and direct Hubble datasets (from cosmic clocks), and Baryon Acoustic Oscillations (BAO) datasets.
- This lets us compare these new ideas about the Universe to the $\Lambda $CDM model in a number of different possible ways.
