# Cosmological model-independent test of $$\varLambda $$ΛCDM with two-point diagnostic by the observational Hubble parameter data

@article{Cao2017CosmologicalMT, title={Cosmological model-independent test of \$\$\varLambda \$\$$\Lambda$CDM with two-point diagnostic by the observational Hubble parameter data}, author={Shulei Cao and Xiao-Wei Duan and Xiao-Lei Meng and Tong-Jie Zhang}, journal={The European Physical Journal C}, year={2017}, volume={78}, pages={1-16} }

Aiming at exploring the nature of dark energy (DE), we use forty-three observational Hubble parameter data (OHD) in the redshift range $$0 < z \leqslant 2.36$$0<z⩽2.36 to make a cosmological model-independent test of the $$\varLambda $$ΛCDM model with two-point $$Omh^2(z_{2};z_{1})$$Omh2(z2;z1) diagnostic. In $$\varLambda $$ΛCDM model, with equation of state (EoS) $$w=-1$$w=-1, two-point diagnostic relation $$Omh^2 \equiv \varOmega _{\mathrm{m}}h^2$$Omh2≡Ωmh2 is tenable, where $$\varOmega _…
