Re-examination of the Hubble Constant from the Sunyaev-Zel'dovich   Effect: Implication for Cosmological Parameters
  We performed a systematic and comprehensive estimate of the Hubble constant $H_0$ via the Sunyaev-Zel'dovich temperature decrement and the X-ray measurements for clusters up to the redshift $z=0.541$, with particular attention to its dependence on the density parameter $\Omega_0$, and the cosmological constant $\lambda_0$. The resulting values of $H_0$ are largely consistent with that derived from the Cepheid distance for nearby galaxies. We discuss how the angular diameter distance $d_A$ vs. $z$ diagram from the accurate SZ measurements of high-$z$ clusters can distinguish the values of $\Omega_0$ and $\lambda_0$.
