title={Possible evidences from $H(z)$ parameter data for physics beyond $ Lambda$CDM},
keywords={Habble parameters,; accelerated expansion, $Lambda$CDM},
abstracts={We analyse $H(z)$ parameter data with some conditions by using Lagrange mean value theorem in Calculus. We find that: (1) there exists at least one decelerated phase at 1 $ sigma$ confidence level in the redshift range $(0.38, 0.59)$; (2) the equation of motion of dark energy may be less than $-1$ at 1 $ sigma$ confidence level at some redshifts in the redshift range $(1.3, 1.53)$; (3) there exists at least one accelerated phase at 1 $ sigma$ confidence level in the redshift range $(1.037, 1.944)$. These results may provide possible evidences for physics beyond $ Lambda$CDM.},
