Lattice analysis of semi-leptonic form factors
Abstract
We present preliminary results from simulations done on 170 323 × 64 lattices at β = 6.0 using quenched Wilson fermions. This talk focuses on the Q2 behavior of the form-factors, extrapolation in quark masses, dependence on renormalization scheme, and comparison with heavy-quark effective theory (HQET). Even though we cannot estimate errors due to quenching and discretization, our results are consistent with experimental results for D decays. We present results for the Isgur-Wise function and estimate '(w=1) = 0.97(6).
