Three H(z) parametrizations in f(R, L_m) = R/2 + L_m^λ gravity are constrained via chi-squared minimization on CC and CC+Pantheon data, with derived quantities for deceleration, EoS, energy conditions, statefinders, and thermodynamics shown to be consistent with observations.

Reconstructing the cosmic expansion in $f(R, L_{m})$ gravity via parametrized Hubble function constraints
Three H(z) parametrizations in f(R, L_m) = R/2 + L_m^λ gravity are constrained via chi-squared minimization on CC and CC+Pantheon data, with derived quantities for deceleration, EoS, energy conditions, statefinders, and thermodynamics shown to be consistent with observations.
