FIG. 1: Plateaus on which the matrix element is ex- ex-tracted according to eq. (20) for 5 different values of momenta corresponding to w = 1 (when this matrix element is zero) and four other momenta correspond-ing to w’s given in eq
FIG. 2: Values of Σ 0 and Σ 3 as obtained on all of the lattices used in this work is shown as a function of the light sea quark mass (divided by the physical strange quark mass)
FIG. 3: We show our data for σ k (1) = σ(1, m h ) with m h = λ k+1 m c , and show the result of the fit in 1/m h
FIG. 5: Results for R 0 (q 2 ) = f 0 (q 2 )/f + (q 2 ) presented in this paper in the case of B s → D s are linearly fit to the form R 0 (q 2 ) = 1−αq 2
