We propose a method for evaluating the slope (and higher derivatives) of the Isgur-Wise function at the zero recoil point using lattice simulations. These derivatives are required for the extrapolation of the experimental data for B --> D*lnuBAR decays to the zero recoil point, from which the V(cb) element of the CKM-matrix can be determined.

Abstract
We propose a method for evaluating the slope (and higher derivatives) of the Isgur-Wise function at the zero recoil point using lattice simulations. These derivatives are required for the extrapolation of the experimental data for B --> D*lnuBAR decays to the zero recoil point, from which the V(cb) element of the CKM-matrix can be determined.File allegati a questo prodotto
