Abstract
We present results for form factors of semileptonic decays of D and B mesons in 2+1 flavor lattice QCD using the MILC gauge configurations. With an improved staggered action for light quarks, we successfully reduce the systematic error from the chiral extrapolation. The results for D decays are in agreement with experimental ones. The results for B decays are preliminary. Combining our results with experimental branching ratios, we then obtain the CKM matrix elements |Vcd|, |Vcs| , |Vcb| and |vub|. We also check CKM unitarity, for the first time, using only lattice QCD as the theoretical input.
