From the power spectrum monopole and quadrupole moments around the LOS, we measure the growth of structure parameter f times the amplitude of dark matter density fluctuations σ8 by modeling the Redshift-Space Distortion signal. When the geometrical Alcock-Paczynski effect is also constrained from the same data, we find joint constraints on fσ8, the product of the Hubble constant and the comoving sound horizon at the baryon drag epoch H(z)rs(zd), and the angular distance parameter divided by the sound horizon DA(z)/rs(zd). We find f(zlowz)σ8(zlowz)=0.394±0.062, DA(zlowz)/rs(zd)=6.35±0.19, H(zlowz)rs(zd)=(11.41±0.56)103kms−1 for the LOWZ sample, and f(zcmass)σ8(zcmass)=0.444±0.038, DA(zcmass)/rs(zd)=9.42±0.15, H(zcmass)rs(zd)=(13.92±0.44)103kms−1 for the CMASS sample.
