Cosmological Dynamics of Accelerating Model in $f(T)$ Gravity with Special Form of Deceleration Parameter

Abstract: In this paper, the dynamical behavior of the accelerated expansion of the universe is discussed within the framework of $f(T)$ gravity for a particular form of $f(T)=\alpha (-T)<sup>{n}$. Considering a redshift-dependent parameterization of the deceleration parameter as $$q(z)=q_{0}+ q_{1}\left(\frac{ \ln(N+z)}{z+1}-\ln N \right)$$. We have derived the Hubble parameter in terms of redshift and discussed its effect on other cosmological parameters. Using Bayesian statistical analysis and $\chi<sup>2$-minimization, the median values of the model parameters for both the cosmic chronometer and the combined (CC + Pantheon) dataset have been determined. Further, energy density, pressure, the equation of state for Dark Energy and statefinder diagnostics are analyzed. The current age of the universe is also computed for this model.
