The authors constrain power-law f(T) teleparallel gravity models via logarithmic and log-periodic deceleration parameter ansatzes fitted to cosmic chronometer and Pantheon datasets, finding departure from ΛCDM.
In f(T) gravity with Gong-Zhang EoS parametrization, the fitted model shows transient acceleration followed by future deceleration and satisfies thermodynamic consistency.
f(Q,T) gravity with linear form and affine EoS is constrained by CC, Pantheon+SH0ES and DESI BAO data, yielding a present universe age consistent with Planck within 1σ.
