Shape of the Isgur-Wise function

Abstract: We analyse the shape of the Isgur-Wise function, by computing its slope and constraining the curvature. This was achieved through computation of the first two moments of the elastic (heavy-to-heavy) form factor. We study the finite volume effects of the lattice for two- and three-point correlation functions. In the calculation, the full nonperturbative improvement of Wilson fermions was used (at $\beta=6.2$) on 24^3 \times 64 lattice.
