First lattice calculation of the B-meson binding and kinetic energies
We present the first lattice calculation of the B-meson binding energy \labar and of the kinetic energy -\lambda_1/2 m_Q of the heavy-quark inside the pseudoscalar B-meson. This calculation has required the non-perturbative subtraction of the power divergences present in matrix elements of the Lagra...
